and Russian deployments of non-strategic nuclear weapons, but did not require Washington or Moscow to exchange information about their respective holdings or include a mechanism to verify implementation. The first device, named RDS-1 (which never entered service), was detonated on 29 August 1949 at the Semipalatinsk test site in Kazakhstan, and was meant to convey a political message that the Soviet Union had arrived on the atomic scene
Was Hiroshima Necessary?
"Japan was essentially defeated," he said, and "it would be wrong to attack its cities with atomic bombs as if atomic bombs were simply another military weapon." In a 1960 magazine article, Szilard wrote: "If the Germans had dropped atomic bombs on cities instead of us, we would have defined the dropping of atomic bombs on cities as a war crime, and we would have sentenced the Germans who were guilty of this crime to death at Nuremberg and hanged them." US Strategic Bombing Survey Verdict After studying this matter in great detail, the United States Strategic Bombing Survey rejected the notion that Japan gave up because of the atomic bombings. In its authoritative 1946 report, the Survey concluded: The Hiroshima and Nagasaki bombs did not defeat Japan, nor by the testimony of the enemy leaders who ended the war did they persuade Japan to accept unconditional surrender
Japan protests The test provoked swift condemnation from Japan, which has also protested in the past against tests carried out by the United States, Britain and the USSR. The communique stated the "nuclear explosion of limited power" had been successful and that care had been taken to prevent radioactive fall-out from affecting people living in the remote part of the desert, and those in neighbouring African countries

First-ever atomic bomb developed by Nazi Germany? - English pravda.ru
Some very simple isotope separators we also sent to Moscow ..." The German scientists who worked on the "uranium project" repeatedly said that creation of a nuclear bomb would require a great deal of time which Germany did not have. Back in 1938 the global scientific community was shaken by the news of the discovery of the German physicists Otto Hahn and Fritz Strassmann who found that the core of uranium isotope 235U is in an unstable condition and under certain environmental conditions can be divided into two parts, which release massive amounts of energy
Why did Soviet Union declare war on Japan after the atomic bombs had been dropped? - Quora
Going into the Potsdam Conference, Stalin and Stavka had set a start date for the Soviet attack for August 20 - 25, 1945, with preparations for the attack to be completed by July 25. From point of view of patient only, some chance August 1 to 3, good chance August 4 and 5, and barring unexpected relapse almost certain before August 10.Truman was pleased by this timing since it meant the atomic bombs would be used before the Soviet Union entered the war
It was known that German scientists had carried out heavy-water experiments in an attempt to split the atom, using research facilities in Norway and elsewhere. But it was widely believed that Nazi scientists had been hampered by a lack of pure-grade uranium, which was almost non-existent outside North America and Africa
The Story of the Atom Bomb
By careful purification of uranium and graphite, proper spacing of target and moderator to cut down the size of the pile, the chain reaction should, theoretically at least, be kept under control. Merle Antony Tuve 1901-1982 On January 26th of that year Bohr attended a Conference on Theoretical Physics at George Washington University in Washington, D.C
1946 Atlanta Constitution Atom Bomb Articles
No reply was forthcoming but it was hoped by the Japanese Government that Premier Stalin and Foreign Minister Molotov would transmit to Britain and the Unites States at the Potsdam Conference Japan's desire to discuss peace. Compton, President of Massachusetts Institute of Technology, told a Senate Committee a year ago that Japan had been trying to develop an A-bomb but that the effort failed for two reasons: Japanese physicists reached mistaken conclusions, B-29 attacks demolished the laboratory where such experiments were being conducted
ww2 - Why did the US drop nuclear bombs on a weakened Japan? - History Stack Exchange
The Japanese were tenacious fighters and their tactics of Kamikaze suicide bombers and their courageous defense of their country in engagements such as the Battle of Okinawa, lend substantial credibility to this claim. Wallace, Semaphore, jwenting, Pieter Geerkens Oct 9 '14 at 6:25 Many good questions generate some degree of opinion based on expert experience, but answers to this question will tend to be almost entirely based on opinions, rather than facts, references, or specific expertise
America's Reaction to the Atomic Bomb
We could prohibit foreign universitites from experimenting in dangerous directions, and counter by offering fellowships at our own universities for certain talented foreigners. Hachiya, as many of the people of Hiroshima, was a broken man, devoid of hope and spirit: "I found myself accepting whatever was told me with equanimity and a detachment I would have never believed possible
The Defense Department includes in this stockpile active warheads which are operational and deployed or ready to be deployed, and inactive warheads which are maintained "in a non-operational status, and have their tritium bottle removed." It does not include warheads that have been retired and are awaiting dismantlement. Israel has not publicly conducted a nuclear test, does not admit to or deny having nuclear weapons, and states that it will not be the first to introduce nuclear weapons in the Middle East
(For an excellent account of how Bohr spread the news of fission to the U.S., see Roger Stuewer, Bringing the News of Fission to America, Physics Today, Oct. Bohr once summarized his approach to life, in his softspoken manner, when he said: "Every valuable human being must be a radical and a rebel, for what he must aim at is to make things better than they are..." (quoted in Nielson, pg
Hiroshima and the Cold War
It is almost certain, however, that this thesis is not true in such a simplistic way - all the evidence shows that Stalin knew the Americans were working on the atomic bomb. However, he also announced that the USA would be seeking defensive military bases, and that he did not intend to share the secrets of the atomic bomb with anybody

Research on nuclear weapon design began at the Institute of Physics and Atomic Energy in Beijing, and a uranium enrichment plant was constructed in Lanzhou to produce weapon-grade uranium.Mao and KhrushchevWith the cooling of Sino-Soviet relations in the late 1950s, the Soviet Union withdrew all assistance
Significant industrial, political, and military installations further east would require one-way missions until the Soviets had an aerial refueling capability. intelligence analysis, which for several years had asserted that the Soviets were unlikely to have the bomb before mid-1953, although mid-1950 was also possible
Britain developed its own atom bomb to remain a great power and avoid complete dependence on the United States, which was refusing to share atomic information. The bomb was put in an anchored frigate, HMS Pym, and when it exploded at 8am local time on October 3rd thousands of tons of rock, mud and sea-water were blasted into the air
1964: China's first atomic bomb explodes
On the same day, the Chinese government made a solemn promise to the world that it developed nuclear weapons only for the purpose of self-defense and safeguarding national security
By that time a sophisticated extraction process based on solvent extraction with tributyl phosphate, similar to the American Purex process, had been fully developed. These events acted to make France deeply suspicious of relying on allies for support, an attitude instrumental in France's later decision to abandon NATO's defense structure and develop its own independent nuclear deterrent
The soviet exploded its first atomic bomb in 1949, how did the United States react to this? - Homework Help - eNotes.com
The first thing that the US did was to propose a plan where both the US and the Soviet Union would turn over all their weapons to the United Nations so that neither nation would be able to use the weapons. Our secondary reaction, then was to develop our technology further, and a hydrogen thermonuclear device along with nuclear missiles would become realities within 6 years of the Soviet bomb test
Key Issues: Nuclear Weapons: History: Pre Cold War: Hiroshima and Nagasaki: Decision: Chronology
The Emperor's announcement is hard to understand because he speaks in archaic court Japanese, but one fact is understood: "Moreover, the enemy has begun to employ a new and most cruel bomb, the power of which to damage is indeed incalcuable, taking the toll of many innocent lives." August 15 New York Times reports, "Russia's entry into the Japanese war was the decisive factor in speeding its end and would have been so, even if no atomic bombs had been dropped, is the opinion of Major-General Claire Chennault .." August 24 Soviet Union announces that the Japanese Manchurian Army has surrendered. April 29 In a report entitled Unconditional Surrender , the Joint Intelligence Committee informs the Joint Chiefs of Staff that "numbers of informed Japanese, both military and civilian, already realize the inevitability of absolute defeat." May 8 War in Europe ends
Nuclear Weapons - China Nuclear Forces
The combination of China's few nuclear weapons and technological factors such as range, accuracy, and response time might further limit the effectiveness of nuclear strikes against counterforce targets. The decision to develop an independent strategic nuclear force was made no later than early 1956 and was to be implemented within the Twelve-Year Science Plan presented in September 1956 to the Eighth Congress of the CCP
Work by Otto Frisch and Rudolf Peierls in Febuary 1940, and the MAUD Committee (a code name chosen from the first name of one member's nanny) report showed the feasibility of fission weapons
Atomic Bomb: Decision -- Truman Tells Stalin, July 24, 1945
Explaining that he wanted to be as informal and casual as possible, Truman said during a break in the proceedings that he would stroll over to Stalin and nonchalantly inform him. A new bomb! Of extraordinary power! Probably decisive on the whole Japanese war! What a bit of luck! This was my impression at the moment, and I was sure that he had no idea of the significance of what he was being told
October, 24, Soviet ships reach the quarantine line, but receive radio orders from Moscow to hold their positions while being backed up by a Soviet submarine. The profound ideological differences between the USSR and the United States were problematic and made worse by Joseph Stalin, who ruled the USSR from 1929 to 1953 as a ruthless dictator
During most of these hours the two of us journeyed from the control house out into the darkness to look at the stars and to assure each other that the one or two visible stars were becoming brighter. Our long range weather predictions had indicated that we could expect weather favorable for our tests beginning on the morning of the 17th and continuing for four days
When did Russia test their atomic bomb
Following on the heels of Thales's work was Democritus (460-370 B.C.), a Greek philosopher who is widely called the "father of the atom." While Democritus did not have experimental proof to support him, he maintained that all matter must consist of a number of fundamental pieces. Some elements do not have a constant atomic weight, but rather the atomic weight fluctuates according to the physical and chemical nature and history of that specific element

The tests conducted were with a fission device, a low-yield device, and a thermonuclear device.'' ''The measured yields are in line with expected values,'' he said. Vajpayee's principal secretary, Brajesh Mishra, said afterward that the tests had established ''that India has a proven capability for a weaponized nuclear program.'' Mr
McMahon (D) Ct., chairman of the Senate-House Atomic Energy Committee, and several other members of Congress suggested anew that the vital hour has arrived for President Truman to meet with Premier Stalin. 23 (AP)-An atomic explosion has occurred in Russia--a fateful portent that the Soviets have broken an American A-bomb monopoly on which the non-Communists world depended so heavily
However, by the 1950s the United States had established a dedicated test site (Nevada Test Site) and was also using a site in the Marshall Islands (Pacific Proving Grounds) for extensive nuclear testing. But warmer relations between the Soviet Union and the United States from the mid-1980s prepared the way, as did the fall of the Berlin Wall in 1989 and the 1991 dissolution of the Soviet Union, which was superseded by the Russian Federation
The feeling of many could be expressed by ''Lord, I believe; help Thou mine unbelief.' We were reaching into the unknown and we did not know what might come of it. At twenty minutes before zero hour, General Groves left for his station at the base camp, first because it provided a better observation point and second, because of our rule that he and I must not be together in situations where there is an element of danger, which existed at both points
In Hanford, Washington, three reactors were built to extract plutonium (another element with atoms that could be split) from a non-fissionable type of uranium. They began to suspect that Fermi hadn't created a new element at all but might have actually split the uranium atom in two -- at that point a barely imaginable event

Also like the American program, the idea of amplifying the yield of a fission bomb by igniting a limited fusion reaction in a lithium-6 deuteride blanket also arose. The quantity of radioactive debris that leaked into the atmosphere was so insignificant that the possibility of its fallout outside the territorial limits of the Soviet Union should be excluded
Cold War Museum
President Truman responded by reevaluating the United States position in the world and called for the United States to build up its conventional and nuclear weapons to halt the spread of Soviet influence around the globe. The impact that the possession of nuclear weapons by the Soviet Union had upon the United States was that it caused Americans to question their own safety
