H-bomb tension from cold war

During the cold war the H-bomb was a topic not to be talked about and sort of secret called the Manhattan project. President Harry S. Truman announced that work on the hydrogen bomb was to be continued in 1950. The Soviet Union was on defense and paranoid wondering if America was planning to fire that bomb towards Russian territory. Although all americans were'nt for the bombs development such as J. Robert Oppenheimer. They felt as it was danger to humanity as a whole. This was a big part of the cold war on who would pull the trigger first on the bomb. The Soviet Union had to be more paranoid because America had a history of firing bombs such as Hiroshima. The H-Bomb forced russian and American leaders to make tough decisions.
