Cold war means a military stand-off. Fighting with nuclear weapons generally insured that such a war could only result in "mutually assured destruction" to both combatants. Consequently, we tried to have the best weapon in case we had to use it. We believed that the side that struck first might have the best chance of surviving; we called, "first strike capability."
Nuclear arms race.
Eventually there were so many nuclear weapons, total destruction of the Earth was possible. The term "Mutually assured destruction (MAD)" was used to describe the resulting holocaust.
no, but they did help the US work on the Manhattan Project, so they had the classified data on how to build them.
The secret U.S. program to develop nuclear weapons during World War II was called the Manhattan Project. Initiated in 1942, it involved collaboration among scientists, engineers, and military personnel to build atomic bombs. The project ultimately led to the development of the first nuclear weapons, which were dropped on Hiroshima and Nagasaki in 1945.
United States of America. Why? Because it has over 160 Nuclear reactors to produce Plutonium and Tritium. This rapidly alows engineers to construct more warheads.
To get nuclear weapons, you must build the Manhattan Project.
Nuclear arms race.
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
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.
Your questions asks for an opinion. My opinion is no. The knowledge of how to build a nuclear weapon is out there. There are too many people with different views and values for nuclear weapons to just go away.
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.
Japan doesn't want any nuclear weapons.But Japan can easily produce nuclear weapons if it wanted to. It has the technology to build nuclear weapons within 1 year-- probably a few months if it wanted.However, most Japanese people are against nuclear weapons. Therefore, they do not have nuclear weapons.
Mutually assured destruction, called for short (and sensibly so): the M.A.D. Principle.
