Right after their initial use. Two were used in war to end WW2 and nobody has ever used another since in war.
Or were you asking something else?
Because it was not very nice. It kills people
Using large, nuclear weapons, eg. Bombs
Every war that the US has fought except WW2 were fought entirely without using any nuclear weapons.
They never used hydrogen bombs in Japan. They used nuclear bombs which produces gamma rays not the lethal doses of x-rays produced by the hydrogen bomb.
The Treaty on the Non-Proliferation of Nuclear Weapons, also Nuclear Non-Proliferation Treat is a treaty to limit the spread of nuclear weapons.
A lot of heat, blast waves, and radioactivity. Devastation over a large area. Many people killed or injured, and many who die later from radiation or burns.
The long term result of the use of the Atomic bomb by the US in WW2, has been building new and larger nuclear weapons/bombs. Despite the advances in nuclear activity, it can clearly be seen that the "fear" of using the mass destruction of nuclear weapons has been that no more nuclear or atomic bombs have ever been used again.
Nuclear attacks, terrorist attacks...do you mean that kinda stuff? Tbh, America can be easily destroyed just by using a few atomic bombs.
First of all Kid they didn't use Nuclear weapons in WW2...They used two Atomic Bombs
This is a war fought using Atomic weapons. Atomic weapons are weapons that use Nuclear fission explostion producing tremendous pressure and radiation. Later nuclear weapons were called hydrogen bombs that use nuclear fussion.
H. G. Wells in his 1914 novel "The World Set Free" was the first to publish on the use of nuclear bombs in a war, he was the first to use the term atomic bomb to refer to bombs that obtain their energy from inside the atom (rather then from chemical reactions between atoms/molecules).Note: H. G. Wells atomic bombs were not based on using nuclear fission or nuclear fusion (as the real bombs are), as the nucleus of the atom had not yet been discovered and neither nuclear fission nor nuclear fusion had been discovered. As the only method of releasing the energy of the atom known at the time was radioactive decay, H. G. Wells based his atomic bombs (and atomic engines) on a hypothetical method of "accelerated radioactive decay".
Often these terms are used interchangeably to describe "nuclear weapons" since an atomic bomb derives it's energy from a nuclear chain reaction. What you may be referring to is that the original test and subsequent bombs dropped on Japan during WWII were fission bombs with the Trinity test bomb and Nagasaki bomb being implosion style fission bombs using Plutonium and the Hiroshima bomb being a gun style fission bomb using Uranium. Subsequently, the United States began testing the early prototypes of the modern style warheads which are called thermonuclear weapons because they use a fission bomb to ignite a nuclear fusion reaction which produces a substantially larger yield than the initial fission bombs. The first test of a thermonuclear weapon was a hydrogen bomb detonated in 1952. So in terms of yield, the modern style thermonuclear weapons are drastically more efficient than the early fission bombs.
