The U.S developed nuclear weapons to scare the Japanese and end World War 2 for the Americans
----------------------------------------------------------------------------------------------------------------------------------
Wrong!
Actually the U.S. developed nuclear weapons in WW2 in an arms race with the supposed Nazi Germany project to do the same. Unknown to us, the German project soon stalled and concentrated on reactors not bombs. When Germany surrendered in spring 1945 the U.S. project continued as it was so close to finishing. In August the only 2 nuclear bombs used in war were dropped on Japan, prompting their surrender and ending the war.
They were developed to defend against a possible German threat but got used against Japan to end the war.
After the war, development slowed but was prompted by fears of the expansion of Soviet Communism. Development accelerated again after the USSR's 1949 test of their first nuclear bomb, causing an extended arms race.
The Soviet Union began making nuclear weapons because of the fear that the United States might use the nuclear weapons they had built and used during WW2 on the Soviet Union.
The United States began making nuclear weapons during WW2 because of the fear that Nazi Germany might be making nuclear weapons and would rapidly defeat England with them, denying access to a convenient place to mass troops for an invasion of Europe (and also use the nuclear weapons on any invading troops). There was also a fear that eventually Nazi Germany might someday use nuclear weapons on the United States.
Every country that has actually made nuclear weapons made them because of this same fear: that Another Country might have nuclear weapons and use those nuclear weapons to attack them.
The only country ever actually attacked using nuclear weapons (Japan) had no idea that the United States had nuclear weapons and their own project doing the preliminary studies of nuclear fission needed to design nuclear weapons had been stalled for many years just trying to build cyclotrons, due to the unavailability of usable high frequency high power vacuum tubes during WW2 in Japan (a problem that also limited Japan's development of RADAR systems). They were so shocked by the bombings that many Japanese scientists sent to evaluate the damage did not understand what they were seeing and the leadership of Japan initially disbelieved the reports of the scope of the damage done.
Fear. It is called an "arms race". There have been arms races with every weapon type ever made.
The US was almost always ahead of the USSR, however our intelligence was so bad we often suspected we were behind and initiated expensive weapons production programs to make up the perceived gap.
The European countries that were successful in resisting the Soviets joined NATO. NATO was successful because it had more nuclear weapons than the Soviets had, as well as having a system of government that was economically superior to communism.
The Soviets were armed with nuclear weapons, that made them a key player. They had the most and best that were comparable to ours; that made them the leader of the enemy coalition.
Pakistan has about 100 nuclear weapons.
No, Nazi Germany had no nuclear weapons.
1949
a conventional and nuclear military buildup that the Soviets could not afford
all together over the years, somewhere around 100,000. however most of these were recycled to make improved weapons. at the peak of the cold war the soviet stockpile contained over 30,000 nuclear weapons, about 10,000 of these were high yield strategic weapons.
NO! Nuclear weapons don't make and detonate themselves
Do the Russians have nuclear weapons?
There is no specific name for people who create nuclear weapons.
No.
make sure nuclear weapons did not proliferate to nations w/o nuclear weapons
The new country that want to make nuclear weapons. And how to consult with they own weapons
NO.
The US no longer makes nuclear weapons, it only refurbishes existing ones that are wearing out.
Announced US Policy, diected at the Soviet Union, that declared that the US could or would respond with the maximum number of nuclear weapons, if the United States (or key allies) was attacked with one or more nuclear weapons from the Soviet Union or any of its allies. It was designed to deter the Soviets from the use of nuclear weapons.
