Americans dropping the atomic bomb on Japan was not justified. Although Japan bombed Pearl Harbor, the Americans dropped a bomb that was much, much worse on innocent civilians. The atomic bomb caused many deaths when it exploded, but still did years after the war ended, due to cancer from the radiation. I think that America was justified to attack Japan after they bombed Pearl Harbor and killed lots of people, but not to the extent that they did.
Japan did bombed pearl harbor which cases America to get in to the world war. But the bomb that America dropped was a Hydrogen bomb. it was really powerful. and causes a lot of destruction and harm. which is still there until today.
