The Manhattan Project was a secret military project created in 1942 to produce the first US nuclear weapon. It was originally a race against the Germans to be the first to make a bomb.
Eventually, though, Japan was not surrendering in WW2. Japan's system of dying for their country being extremely honorable and having to take part in the war or facing serious consequences made it hard for the US to defeat them. Harry S. Truman ordered this bomb to bring the war to a speedy end. The result was the five-ton bomb over the Japenese city of Hiroshima and eventually Nagasaki.
Other solutions would've been to invade, but Truman must've seen it as losing American lives too and that this was the best way to end the war. We also could've waited before dropping the second bomb on Nagasaki because we heard no news from Japan, but that was just in two days. It was very quick to rush for so many lives.
I hoped this helped! This is what I learned from my teachers but here is a link to more solutions regarding the atomic bomb:
