Yes USA did use nuclear bomb once, they dropped it at two Japanese cities, killing hundred of thousands. Sounds cruels. But few people are aware that without the a bomb, if the war with Japan goes on, it would cost even 5 millions of lives (as some history searchers claim).
that's actually quite wrong, the Japanese had sent messages of surrender, several times through more than one channel, the only condition was the emperor stays emperor, the U.S refused and nuked them instead..
