The US were working on the bomb since 1941 up to 1945 when the first bomb tested.
The US made atomic bombs from 1945 to 1992.
Obama himself is not going to bomb us. He will let terrorists do it though
the us created the atomic bomb
To defend against the possibility of a Nazi atomic bomb, which if Germany succeeded in making it Hitler would order it used against Britain to force them to surrender. It was hoped the US might complete the atomic bomb first, but if not then shortly after so that Germany might also be attacked with them in retaliation for attacking England.
well theoretically you can make a bomb with that capability, the largest nuclear weapons detonated was the Tsar bomba, which destroyed around 30-40 miles of an area, that bomb was measured at around 50MT (megatons) the Soviet Union was going to build another bomb after that with 100MT so it is possible but it would be highly unstable, no one in modern times holds a device that powerful.
