America cant really be compared to esthar that way because at the time of WWII it was not the most technologically advanced country... only after the war was it... America and Russia stole some space travel plans n stuff from germany.

People live in Hiroshima and nagasaki... i saw a video on it and people are still born with mutations that are attributed to radiation or something... furthermore the a bombs actually saved more lives than they put to end because had they not been dropped the casualties generated by a prolonged war would have far exceeded those created by the dropping of the bombs... (interesting side fact the inventor of A-bombs created them as a means of generating energy and went crazy after they were used as tools of war, he died of insanity)
