I’m going to nitpick a bit but FDR was president and made the decision to go to war with Japan over pearl harbor. Truman made the final decision to drop the nuclear weapons on Japan.
Roosevelt had likely a plan since the Manhattan project was under his presidency but Truman inherited that.
I think it’s mostly accepted that the USA did not nuke Japan specifically because of pearl harbor but more to force a rapid surrender. Japan was being extremely stubborn and the estimated loss of US forces was very high to continue the war.
The exhibit at the Hiroshima Peace Museum argues that Truman dropped the bombs to end the war before the Soviets could invade and to avoid the partition of Japan.
