Answer:
I believe that the United States was and wasn't justified to drop the atomic bombs on Hiroshima and Nagasaki
Step-by-step explanation:
It was justified because Japan realized a surprise attack at Pearl Harbor in Hawaii, after two hours of bombing, 18 U.S. ships were sunk or damaged, 188 U.S. aircraft were destroyed, and 2,403 people were killed, all of this happened while the U.S. and Japan were officially engaging in diplomatic negotiations for possible peace in Asia.
It wasn't justified because the two bombings killed between 129,000 and 226,000 people.
