Your question assumes someone would not blow up the world with atomic bombs. That is a fallacy. There are a few humans in this world who would be insane enough to issue enough nuclear bombs in order to destroy the world. They would not be considered "sane rational people" by the rest of the world.
Humanity wants to preserve itself. Therefore people are not inclined to "blow up the world". If a poll was taken around the world you would probably learn that people do not want to end the world via nuclear elimination. They want to live and enjoy peace around the world. That is why people would NOT blow up the world with atomic weapons.
Japan was negotiatin with the Soviet Union as the first atomic bomb was dropped.
Japan never dropped the atomic bomb on anyone. They did not have that technology.
No. Nor did anyone else. Atomic bombs are an invention not a discovery.
Although your question is vague, atomic bombs have come and gone in terms of technology. We now have conventional weapons that are more powerful than the atomic bomb.
Germany had surrendered before the bomb was operational.
I don't think anyone has seen an atomic bomb and lived,but so say about 3 to 4 days.
The Germans did not drop an atomic bomb on Japan or on anyone. It was the US which dropped two atomic bombs on Japan (specifically on the cities of Hiroshima and Nagasaki) in 1945.
very little
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
Instead of the atomic bomb they rather use fire bombs instead because they were sure the atomic bomb will crush the earth crust.
The atomic bomb is an artefact, and so an invention. Maybe you meant to ask who invented the atomic bomb ?
