An explosive device is a device that relies on the exothermic reaction of an explosive material to provide a violent release of energy.
122-739: A nuclear weapon is an explosive device that derives its destructive force from nuclear reactions , either fission (fission bomb) or a combination of fission and fusion reactions ( thermonuclear bomb ), producing a nuclear explosion . Both bomb types release large quantities of energy from relatively small amounts of matter . The first test of a fission ("atomic") bomb released an amount of energy approximately equal to 20,000 tons of TNT (84 TJ ). The first thermonuclear ("hydrogen") bomb test released energy approximately equal to 10 million tons of TNT (42 PJ). Nuclear bombs have had yields between 10 tons TNT (the W54 ) and 50 megatons for
244-513: A misnomer , as their energy comes from the nucleus of the atom, just as it does with fusion weapons. In fission weapons, a mass of fissile material ( enriched uranium or plutonium ) is forced into supercriticality —allowing an exponential growth of nuclear chain reactions —either by shooting one piece of sub-critical material into another (the "gun" method) or by compression of a sub-critical sphere or cylinder of fissile material using chemically fueled explosive lenses . The latter approach,

South Africa is the only country to have independently developed and then renounced and dismantled its nuclear weapons. The Treaty on the Non-Proliferation of Nuclear Weapons aims to reduce the spread of nuclear weapons, but there are different views of its effectiveness. There are two basic types of nuclear weapons: those that derive
488-696: A conference—called for in the manifesto—in Pugwash, Nova Scotia , Eaton's birthplace. This conference was to be the first of the Pugwash Conferences on Science and World Affairs , held in July 1957. By the 1960s, steps were taken to limit both the proliferation of nuclear weapons to other countries and the environmental effects of nuclear testing . The Partial Nuclear Test Ban Treaty (1963) restricted all nuclear testing to underground nuclear testing , to prevent contamination from nuclear fallout, whereas
610-610: A core part of the Belarusian national identity, with Belarus continuing to refer to itself as the "partisan republic" since the 1970s. Following the war, many former Soviet partisans entered positions of government, among them Pyotr Masherov and Kirill Mazurov , both of whom were First Secretary of the Communist Party of Byelorussia. Until the late 1970s, the Belarusian government was almost entirely composed of former partisans. Numerous pieces of media have been made about
732-532: A disputed election took place on 8 January 1922, and the territory was annexed to Poland. Żeligowski later in his memoir which was published in London in 1943 condemned the annexation of the Republic by Poland, as well as the policy of closing Belarusian schools and general disregard of Marshal Józef Piłsudski 's confederation plans by Polish ally. In January 1919, a part of Belarus under Bolshevik Russian control
854-458: A faster and less vulnerable attack, the development of long-range intercontinental ballistic missiles (ICBMs) and submarine-launched ballistic missiles (SLBMs) has given some nations the ability to plausibly deliver missiles anywhere on the globe with a high likelihood of success. More advanced systems, such as multiple independently targetable reentry vehicles (MIRVs), can launch multiple warheads at different targets from one missile, reducing
976-614: A few nations possess such weapons or are suspected of seeking them. The only countries known to have detonated nuclear weapons—and acknowledge possessing them—are (chronologically by date of first test) the United States , the Soviet Union (succeeded as a nuclear power by Russia ), the United Kingdom , France , China , India , Pakistan , and North Korea . Israel is believed to possess nuclear weapons, though, in
1098-555: A fission bomb to initiate them. Such a device might provide a simpler path to thermonuclear weapons than one that required the development of fission weapons first, and pure fusion weapons would create significantly less nuclear fallout than other thermonuclear weapons because they would not disperse fission products. In 1998, the United States Department of Energy divulged that the United States had, "...made
1220-418: A fusion weapon as of January 2016, though this claim is disputed. Thermonuclear weapons are considered much more difficult to successfully design and execute than primitive fission weapons. Almost all of the nuclear weapons deployed today use the thermonuclear design because it results in an explosion hundreds of times stronger than that of a fission bomb of similar weight. Thermonuclear bombs work by using

Because the effect is most effectively produced by high altitude nuclear detonations (by military weapons delivered by air, though ground bursts also produce EMP effects over a localized area), it can produce damage to electronics over a wide, even continental, geographical area. Research has been done into the possibility of pure fusion bombs : nuclear weapons that consist of fusion reactions without requiring

Since 1996, the United States has had a policy of allowing the targeting of its nuclear weapons at terrorists armed with weapons of mass destruction . Robert Gallucci argues that although traditional deterrence is not an effective approach toward terrorist groups bent on causing a nuclear catastrophe, Gallucci believes that "the United States should instead consider
1586-425: A nuclear war between two nations would result in mutual annihilation. From this point of view, the significance of nuclear weapons is to deter war because any nuclear war would escalate out of mutual distrust and fear, resulting in mutually assured destruction . This threat of national, if not global, destruction has been a strong motivation for anti-nuclear weapons activism. Critics from the peace movement and within
1708-411: A nuclear weapon from another country by threatening nuclear retaliation is known as the strategy of nuclear deterrence . The goal in deterrence is to always maintain a second strike capability (the ability of a country to respond to a nuclear attack with one of its own) and potentially to strive for first strike status (the ability to destroy an enemy's nuclear forces before they could retaliate). During
1830-465: A nuclear weapon is a gravity bomb dropped from aircraft ; this was the method used by the United States against Japan in 1945. This method places few restrictions on the size of the weapon. It does, however, limit attack range, response time to an impending attack, and the number of weapons that a country can field at the same time. With miniaturization, nuclear bombs can be delivered by both strategic bombers and tactical fighter-bombers . This method
1952-408: A nuclear weapon to its target is an important factor affecting both nuclear weapon design and nuclear strategy . The design, development, and maintenance of delivery systems are among the most expensive parts of a nuclear weapons program; they account, for example, for 57% of the financial resources spent by the United States on nuclear weapons projects since 1940. The simplest method for delivering
2074-433: A nuclear weapon with suitable materials (such as cobalt or gold ) creates a weapon known as a salted bomb . This device can produce exceptionally large quantities of long-lived radioactive contamination . It has been conjectured that such a device could serve as a "doomsday weapon" because such a large quantity of radioactivities with half-lives of decades, lifted into the stratosphere where winds would distribute it around
2196-420: A policy of expanded deterrence, which focuses not solely on the would-be nuclear terrorists but on those states that may deliberately transfer or inadvertently leak nuclear weapons and materials to them. By threatening retaliation against those states, the United States may be able to deter that which it cannot physically prevent.". Graham Allison makes a similar case, arguing that the key to expanded deterrence

Only six countries—the United States , Russia , the United Kingdom , China , France , and India —have conducted thermonuclear weapon tests. Whether India has detonated a "true" multi-staged thermonuclear weapon is controversial. North Korea claims to have tested
2562-574: A staggering quarter of the prewar population . In the 1990s some raised the estimate even higher, to 2.7 million. The Jewish population of Belarus was devastated during the Holocaust and never recovered. The population of Belarus did not regain its pre-war level until 1971. Belarus was also hit hard economically, losing around half of its economic resources. The borders of the Byelorussian SSR and Poland were redrawn, in accord with

A major challenge in all nuclear weapon designs is to ensure that a significant fraction of the fuel is consumed before the weapon destroys itself. The amount of energy released by fission bombs can range from the equivalent of just under a ton to upwards of 500,000 tons (500 kilotons ) of TNT (4.2 to 2.1 × 10 GJ). All fission reactions generate fission products ,

9150-547: The United States have all imposed sanctions against Belarus because of the rigged election and political oppression during the ongoing protests in the country. Further sanctions were imposed in 2022 following the country's role and complicity in the Russian invasion of Ukraine; Russian troops were allowed to stage part of the invasion from Belarusian territory. These include not only corporate offices and individual officers of government but also private individuals who work in
9272-525: The United States. Small, two-man portable tactical weapons (somewhat misleadingly referred to as suitcase bombs ), such as the Special Atomic Demolition Munition , have been developed, although the difficulty of combining sufficient yield with portability limits their military utility. Nuclear warfare strategy is a set of policies that deal with preventing or fighting a nuclear war. The policy of trying to prevent an attack by
9394-465: The adoption of a new constitution in 1994, Alexander Lukashenko was elected Belarus's first president in the country's first and only free election after independence, serving as president ever since. Lukashenko heads a highly centralized authoritarian government. Belarus ranks low in international measurements of freedom of the press and civil liberties . It has continued several Soviet-era policies, such as state ownership of large sections of
9516-535: The area by 1,000 BC. The Zarubintsy culture later became widespread at the beginning of the 1st millennium . In addition, remains from the Dnieper–Donets culture were found in Belarus and parts of Ukraine . The region was first permanently settled by Baltic tribes in the 3rd century. Around the 5th century, the area was taken over by the Slavs. The takeover was partially due to the lack of military coordination of
9638-412: The borders of Belarus took their modern shape in 1939, when some lands of the Second Polish Republic were reintegrated into it after the Soviet invasion of Poland , and were finalized after World War II. During World War II, military operations devastated Belarus, which lost about a quarter of its population and half of its economic resources. In 1945, the Byelorussian SSR became a founding member of
9760-484: The chance of a successful missile defense . Today, missiles are most common among systems designed for delivery of nuclear weapons. Making a warhead small enough to fit onto a missile, though, can be difficult. Tactical weapons have involved the most variety of delivery types, including not only gravity bombs and missiles but also artillery shells, land mines , and nuclear depth charges and torpedoes for anti-submarine warfare . An atomic mortar has been tested by
9882-582: The country's name was changed to the Republic of Belarus on 25 August 1991. Stanislav Shushkevich , the chairman of the Supreme Soviet of Belarus, met with Boris Yeltsin of Russia and Leonid Kravchuk of Ukraine on 8 December 1991 in Białowieża Forest to formally declare the dissolution of the Soviet Union and the formation of the Commonwealth of Independent States . In January 1992,
10004-435: The creation of nuclear fallout than fission reactions, but because all thermonuclear weapons contain at least one fission stage, and many high-yield thermonuclear devices have a final fission stage, thermonuclear weapons can generate at least as much nuclear fallout as fission-only weapons. Furthermore, high yield thermonuclear explosions (most dangerously ground bursts) have the force to lift radioactive debris upwards past
10126-491: The date for said referendum was delayed by six months. However, with no evidence to suggest such, the Supreme Council rejected the petition on the grounds of massive irregularities. Elections for the Supreme Council were set for March 1994. A new law on parliamentary elections failed to pass by 1993. Disputes over the referendum were accredited to the largely conservative Party of Belarusian Communists , which controlled
10248-770: The days of the Russian Empire , and the Russian Tsar was usually styled "the Tsar of All the Russias", as Russia or the Russian Empire was formed by three parts of Russia—the Great , Little , and White . This asserted that the territories are all Russian and all the peoples are also Russian; in the case of the Belarusians, they were variants of the Russian people. After the Bolshevik Revolution in 1917,
10370-455: The decision process. The prospect of mutually assured destruction might not deter an enemy who expects to die in the confrontation. Further, if the initial act is from a stateless terrorist instead of a sovereign nation, there might not be a nation or specific target to retaliate against. It has been argued, especially after the September 11, 2001, attacks , that this complication calls for
10492-404: The economy, with inflation reaching 108.7%. Around the same time the 2011 Minsk Metro bombing occurred in which 15 people were killed and 204 were injured. Two suspects, who were arrested within two days, confessed to being the perpetrators and were executed by shooting in 2012. The official version of events as publicised by the Belarusian government was questioned in the unprecedented wording of
10614-469: The energy of a fission bomb to compress and heat fusion fuel. In the Teller-Ulam design , which accounts for all multi-megaton yield hydrogen bombs, this is accomplished by placing a fission bomb and fusion fuel ( tritium , deuterium , or lithium deuteride ) in proximity within a special, radiation-reflecting container. When the fission bomb is detonated, gamma rays and X-rays emitted first compress
10736-464: The faster we shall build communism." Between Stalin's death in 1953 and 1980, Belarusian politics was dominated by former members of the Soviet partisans, including First Secretaries Kirill Mazurov and Pyotr Masherov. Mazurov and Masherov oversaw Belarus's rapid industrialisation and transformation from one of the Soviet Union's poorest republics into one of its richest. In 1986, the Byelorussian SSR
10858-455: The fission bomb core. The external method of boosting enabled the USSR to field the first partially thermonuclear weapons, but it is now obsolete because it demands a spherical bomb geometry, which was adequate during the 1950s arms race when bomber aircraft were the only available delivery vehicles. The detonation of any nuclear weapon is accompanied by a blast of neutron radiation . Surrounding
10980-478: The former lands of Kievan Rus' , including the territories of modern-day Belarus and Ukraine . On 2 February 1386, the Grand Duchy of Lithuania and the Kingdom of Poland were joined in a personal union through a marriage of their rulers . This union set in motion the developments that eventually resulted in the formation of the Polish–Lithuanian Commonwealth , created in 1569 by the Union of Lublin . In
11102-420: The fusion fuel, then heat it to thermonuclear temperatures. The ensuing fusion reaction creates enormous numbers of high-speed neutrons , which can then induce fission in materials not normally prone to it, such as depleted uranium . Each of these components is known as a "stage", with the fission bomb as the "primary" and the fusion capsule as the "secondary". In large, megaton-range hydrogen bombs, about half of
11224-535: The globe, would make all life on the planet extinct. In connection with the Strategic Defense Initiative , research into the nuclear pumped laser was conducted under the DOD program Project Excalibur but this did not result in a working weapon. The concept involves the tapping of the energy of an exploding nuclear bomb to power a single-shot laser that is directed at a distant target. During
11346-654: The legitimate president of Belarus and the Lithuanian government has allotted a residence for main opposition candidate Sviatlana Tsikhanouskaya and other members of the Belarusian opposition in Vilnius . Neither is Lukashenko recognized as the legitimate president of Belarus by the European Union, Canada, the United Kingdom or the United States. The European Union, Canada, the United Kingdom, and
11468-495: The majority of their energy from nuclear fission reactions alone, and those that use fission reactions to begin nuclear fusion reactions that produce a large amount of the total energy output. All existing nuclear weapons derive some of their explosive energy from nuclear fission reactions. Weapons whose explosive output is exclusively from fission reactions are commonly referred to as atomic bombs or atom bombs (abbreviated as A-bombs ). This has long been noted as something of
11590-407: The midst of the Cold War. It highlighted the dangers posed by nuclear weapons and called for world leaders to seek peaceful resolutions to international conflict. The signatories included eleven pre-eminent intellectuals and scientists, including Albert Einstein , who signed it just days before his death on April 18, 1955. A few days after the release, philanthropist Cyrus S. Eaton offered to sponsor
11712-544: The military establishment have questioned the usefulness of such weapons in the current military climate. According to an advisory opinion issued by the International Court of Justice in 1996, the use of (or threat of use of) such weapons would generally be contrary to the rules of international law applicable in armed conflict, but the court did not reach an opinion as to whether or not the threat or use would be lawful in specific extreme circumstances such as if
11834-408: The missiles before they land or implementing civil defense measures using early-warning systems to evacuate citizens to safe areas before an attack. Weapons designed to threaten large populations or to deter attacks are known as strategic weapons . Nuclear weapons for use on a battlefield in military situations are called tactical weapons . Critics of nuclear war strategy often suggest that
11956-689: The name "Belarus". Despite significant efforts, the state ceased to exist, primarily because the territory was continually dominated by the Imperial German Army and the Imperial Russian Army in World War I , and then the Bolshevik Red Army . It existed from only 1918 to 1919 but created prerequisites for the formation of a Belarusian state. The choice of name was probably based on the fact that core members of
12078-419: The naturally regenerating forest 2% was reported to be primary forest (consisting of native tree species with no clearly visible indications of human activity) and around 16% of the forest area was found within protected areas. For the year 2015, 100% of the forest area was reported to be under public ownership . Belarus borders five countries: Latvia to the north, Lithuania to the northwest, Poland to
12200-402: The newly formed government were educated in tsarist universities, with corresponding emphasis on the ideology of West-Russianism. The Republic of Central Lithuania was a short-lived political entity, which was the last attempt to restore Lithuania to the historical confederacy state (it was also supposed to create Lithuania Upper and Lithuania Lower). The republic was created in 1920 following
12322-428: The remains of the split atomic nuclei. Many fission products are either highly radioactive (but short-lived) or moderately radioactive (but long-lived), and as such, they are a serious form of radioactive contamination . Fission products are the principal radioactive component of nuclear fallout . Another source of radioactivity is the burst of free neutrons produced by the weapon. When they collide with other nuclei in
12444-435: The return to Orthodox Christianity of Belarusian Uniates . Belarusian language was banned in schools while in neighboring Samogitia primary school education with Samogitian literacy was allowed. In a Russification drive in the 1840s, Nicholas I prohibited the use of the Belarusian language in public schools, campaigned against Belarusian publications, and tried to pressure those who had converted to Catholicism under
12566-591: The southeastern regions) was affected by radiation fallout. The United Nations and other agencies have aimed to reduce the level of radiation in affected areas, especially through the use of caesium binders and rapeseed cultivation, which are meant to decrease soil levels of caesium-137 . In Belarus forest cover is around 43% of the total land area, equivalent to 8,767,600 hectares (ha) of forest in 2020, up from 7,780,000 hectares (ha) in 1990. In 2020, naturally regenerating forests covered 6,555,600 hectares (ha), and planted forests covered 2,212,000 hectares (ha). Of
12688-473: The staged rebellion of soldiers of the 1st Lithuanian–Belarusian Division of the Polish Army under Lucjan Żeligowski . Centered on the historical capital of the Grand Duchy of Lithuania , Vilna ( Lithuanian : Vilnius , Polish : Wilno ), for 18 months the entity served as a buffer state between Poland , upon which it depended, and Lithuania, which claimed the area. After a variety of delays,
12810-475: The state split into independent principalities. The Battle on the Nemiga River in 1067 was one of the more notable events of the period, the date of which is considered the founding date of Minsk . Many early principalities were virtually razed or severely affected by a major Mongol invasion in the 13th century, but the lands of modern-day Belarus avoided the brunt of the invasion and eventually joined
12932-402: The surrounding material, the neutrons transmute those nuclei into other isotopes, altering their stability and making them radioactive. The most commonly used fissile materials for nuclear weapons applications have been uranium-235 and plutonium-239 . Less commonly used has been uranium-233 . Neptunium-237 and some isotopes of americium may be usable for nuclear explosives as well, but it
13054-497: The survival of the state were at stake. Another deterrence position is that nuclear proliferation can be desirable. In this case, it is argued that, unlike conventional weapons, nuclear weapons deter all-out war between states, and they succeeded in doing this during the Cold War between the U.S. and the Soviet Union . In the late 1950s and early 1960s, Gen. Pierre Marie Gallois of France, an adviser to Charles de Gaulle , argued in books like The Balance of Terror: Strategy for
13176-476: The term White Russia caused some confusion, as it was also the name of the military force that opposed the red Bolsheviks. During the period of the Byelorussian SSR, the term Byelorussia was embraced as part of a national consciousness. In western Belarus under Polish control, Byelorussia became commonly used in the regions of Białystok and Grodno during the interwar period. The term Byelorussia (its names in other languages such as English being based on
13298-547: The vote in the first round and 80% in the second, defeating Vyacheslav Kebich who received 14% of the vote. The elections were the first and only free elections in Belarus after independence. The 2000s saw some economic disputes between Belarus and its primary economic partner, Russia. The first one was the 2004 Russia–Belarus energy dispute when Russian energy giant Gazprom ceased the import of gas into Belarus because of price disagreements. The 2007 Russia–Belarus energy dispute centered on accusations by Gazprom that Belarus
13420-446: The weapon system and difficult to defend against the delivery of the weapon during a potential conflict. This can mean keeping weapon locations hidden, such as deploying them on submarines or land mobile transporter erector launchers whose locations are difficult to track, or it can mean protecting weapons by burying them in hardened missile silo bunkers. Other components of nuclear strategies included using missile defenses to destroy
13542-586: The word derives from the Old Prussian name Gudwa , which, in turn, is related to the form Żudwa , which is a distorted version of Sudwa, Sudovia. Sudovia , in its turn, is one of the names of the Yotvingians . Another hypothesis connects the word with the Gothic Kingdom that occupied parts of the territory of modern Belarus and Ukraine in the 4th and 5th centuries. The self-naming of Goths
13664-627: The world where there exists a single nuclear-weapon state. Aside from the public opinion that opposes proliferation in any form, there are two schools of thought on the matter: those, like Mearsheimer, who favored selective proliferation, and Waltz, who was somewhat more non- interventionist . Interest in proliferation and the stability-instability paradox that it generates continues to this day, with ongoing debate about indigenous Japanese and South Korean nuclear deterrent against North Korea . The threat of potentially suicidal terrorists possessing nuclear weapons (a form of nuclear terrorism ) complicates
13786-525: The years following the union, the process of gradual Polonization of both Lithuanians and Ruthenians gained steady momentum. In culture and social life, both the Polish language and Catholicism became dominant, and in 1696, Polish replaced Ruthenian as the official language, with Ruthenian being banned from administrative use. However, the Ruthenian peasants continued to speak their native language. Also,
13908-623: The yield comes from the final fissioning of depleted uranium. Virtually all thermonuclear weapons deployed today use the "two-stage" design described to the right, but it is possible to add additional fusion stages—each stage igniting a larger amount of fusion fuel in the next stage. This technique can be used to construct thermonuclear weapons of arbitrarily large yield. This is in contrast to fission bombs, which are limited in their explosive power due to criticality danger (premature nuclear chain reaction caused by too-large amounts of pre-assembled fissile fuel). The largest nuclear weapon ever detonated,
14030-521: Was Gutans and Gytos , which are close to Gudija. Yet another hypothesis is based on the idea that Gudija in Lithuanian means "the other" and may have been used historically by Lithuanians to refer to any people who did not speak Lithuanian. From 5000 to 2000 BC, the Bandkeramik predominated in what now constitutes Belarus, and the Cimmerians as well as other pastoralists roamed through
14152-519: Was contaminated with most (70%) of the nuclear fallout from the explosion at the Chernobyl power plant located 16 km beyond the border in the neighboring Ukrainian SSR . By the late 1980s, political liberalization led to a national revival, with the Belarusian Popular Front becoming a major pro-independence force. In March 1990, elections for seats in the Supreme Soviet of
14274-591: Was declared the Socialist Soviet Republic of Byelorussia (SSRB) for just two months, but then merged with the Lithuanian Soviet Socialist Republic (LSSR) to form the Socialist Soviet Republic of Lithuania and Belorussia (SSR LiB), which lost control of its territories by August. The Byelorussian Soviet Socialist Republic (BSSR) was created in July 1920. The contested lands were divided between Poland and
14396-405: Was in the late-16th century by Englishman Sir Jerome Horsey , who was known for his close contacts with the Russian royal court. During the 17th century, the Russian tsars used the term to describe the lands added from the Grand Duchy of Lithuania. The term Belorussia (Russian: Белору́ссия , the latter part similar but spelled and stressed differently from Росси́я , Russia ) first rose in
14518-458: Was predominantly inhabited by pagan Balts . An alternative explanation for the name comments on the white clothing the local Slavic population wears. A third theory suggests that the old Rus' lands that were not conquered by the Tatars (i.e., Polotsk, Vitebsk, and Mogilev) had been referred to as White Rus' . A fourth theory suggests that the color white was associated with the west, and Belarus
14640-495: Was siphoning oil off of the Druzhba pipeline that runs through Belarus. Two years later the so-called Milk War , a trade dispute, started when Russia wanted Belarus to recognize the independence of Abkhazia and South Ossetia and through a series of events ended up banning the import of dairy products from Belarus. In 2011, Belarus suffered a severe economic crisis attributed to Lukashenko's government's centralized control of
14762-743: Was the Special Atomic Demolition Munition , or SADM, sometimes popularly known as a suitcase nuke . This is a nuclear bomb that is man-portable, or at least truck-portable, and though of a relatively small yield (one or two kilotons) is sufficient to destroy important tactical targets such as bridges, dams, tunnels, important military or commercial installations, etc. either behind enemy lines or pre-emptively on friendly territory soon to be overtaken by invading enemy forces. These weapons require plutonium fuel and are particularly "dirty". They also demand especially stringent security precautions in their storage and deployment. Small "tactical" nuclear weapons were deployed for use as antiaircraft weapons. Examples include
14884-564: Was the western part of Rus' in the 9th to 13th centuries. The name Rus' is often conflated with its Latin forms Russia and Ruthenia , thus Belarus is often referred to as White Russia or White Ruthenia . The name first appeared in German and Latin medieval literature ; the chronicles of Jan of Czarnków mention the imprisonment of Lithuanian grand duke Jogaila and his mother at " Albae Russiae, Poloczk dicto " in 1381. The first known use of White Russia to refer to Belarus
