Nuclear weapons in the US are all refurbished at PANTEX just east of Amarillo, TX. No new nuclear weapons are built at this time by the US.
Mutually assured destruction, called for short (and sensibly so): the M.A.D. Principle.
Because the men were not around to work and build weapons so the women had to do it!
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.
This is a moot question. At the very end of WW II, the United States had built two nuclear bombs, both of which were ultimately dropped on Japan. That was all they had - a third one would have taken several more months to build. And World War II ended 66 years ago.
To get nuclear weapons, you must build the Manhattan Project.
During WW2, the Manhatton project was accomplished in New Mexico.
Japan did research on nuclear weapons in WW2 but never got near planning to build one, let alone making and testing one.
All the facilities used by the US to prepare the materials for nuclear weapons, build nuclear weapons, design and test new nuclear weapons. This is all lead by the Department Of Energy.
almost anyone that can get the materials
The nuclear weapons of the cold war still exist. They were in responsible controlled hands during the cold war (which is why there wasn't a war). The problem: Keeping them out of un-controlled hands.
yes, but for many reasons they made mistakes that prevented progress. By 1943 they had decided it would not be practical to build nuclear bombs before they won the war with conventional weapons & they scaled their program back to mostly basic research aimed at building nuclear power reactors after they won the war.
Nearly every kind that anyone could think up.
no
stockpiling
either a build up of nuclear weapons, or a buildup in conventional weapons
North Korea already has the nuclear weapons, it is delivery vehicles it is developing.
