The story is long and complicated, too long to do justice to it here. I suggest reading Richard Rhodes' book The Making of the Atomic Bomb.
if by bomb you mean atomic bomb, it was truman. otherwise bombs predate the existence of the US.
I suggest Richard Rhodes book The Making of the Atomic Bomb.1945
Hitler, he was dead before the Bomb was used in warfare.
The atom bomb was not in existence during World War One, also known as "The Great War".
No atomic bombs were used in the Korean War and there were never any plans to use them. Possibly the existence of atomic weapons had some small effect.
The attack at Pearl was the start of the war, not the end. The end came 4 years later with the atomic bomb.
If you consider the US atomic bomb is a Christian bomb, the French atomic bomb is also Christian bomb and so on, then you can name the Pakistani atomic bomb an Islamic bomb.
how was the atomic bomb repaired
It was an atomic bomb. The city was devastated. The damage came from the heat and the radiation.
almost all originally came from mines.
The atomic bomb is an artefact, and so an invention. Maybe you meant to ask who invented the atomic bomb ?
18th May1998, but its not atomic bomb (its nuclear bomb)
