What country used nuclear weapons first?
The U.S. is first to have nuclear weapons, having nukes since
1945. The Soviet Union followed the U.S. by developing and testing
their first nuke in 1949. Both nation started making hydrogen bombs
(nukes using nuclear fission to explode) starting in the mid-1950s.
Excuse me replying with a question, but were the Atomic bombs
dropped on Japan in 1945 Nuclear weapons ? I am assuming they were,
but do not know of the differentiation.
