President Roosevelt knew it would take at least a million marines to take the main island of Japan, we could have won without the bomb, but we would have taken thousands of unnecessary casualties.
Yes, but it would have continued at least one more year (possibly as long as ten more years) and involved at least a couple million more deaths (possibly over a hundred million more deaths, at which point Japan's population would have fallen to just over 1% of its prewar population). Japan would have been partitioned between the US and USSR into a southern democratic Japanand a northern communist totalitarian Japan; like Germany, Korea, Vietnam, etc. were.
Also the US had already 100% secretly committed to using chemical weapons (a violation of the Geneva Convention) on Japan if during the invasion they resisted as ferociously as they had on the last few island. The atomic bomb was seen as a way to avoid having to do this.
In the tradeoffs of war, less than 200,000 atomic bomb deaths to end the war promptly is far better than millions of deaths and a war possibly dragging on years!
However the US was far from certain the atomic bomb would end the war promptly. We had already drawn up plans to drop a total of 23 atomic bombs on Japan in 1945 (fortunately only 2 were needed) and the Manhattan Project had all the factories built and running at full capacity to fulfill this plan by the end of July 1945. Considering this plan and the fact that by November 1945 the factories were scheduled to increase production from 3 bombs a month to 7 bombs a month (by changing from a plutonium core to a composite plutonium/uranium core to take advantage of the uranium enrichment capacity no longer being used as only one Little boy uranium bomb was planned to be used in the war), in 1946 we could have probably continued dropping 7 atomic bombs a month on Japan and possible additional improvements might have increased this should the war have continued that long.
The first atomic bomb was dropped on Hiroshima, Japan ; another on Nagasaki, Japan, 3 days later.
Japan refused to surrender. Japan did not believe in surrender, and hated people who did surrender instead of dying to the last person. Pres. Truman dropped two atomic bombs on Japan and Japan surrendered. It was either two atomic bombs or invasion of Japan. Invasion of Japan would mean that the war would last another year and kill a lot more people than the atomic bombs did. Japan surrendered after Nagasaki was bombed, not after Hiroshima. It was either the atomic bombs or invasion. Atomic bombs were the lesser of two evils.
2 atomic bombs and 2 million HE bombs and 5 million incendiary fire bombs
The atomic bombs were delivered by the USS Indianoppolis

there were many
The first atomic bomb was dropped on Hiroshima, Japan ; another on Nagasaki, Japan, 3 days later.
The first atomic bomb used in war was dropped on Hiroshima, Japan. The delivery method was via an airplane named the 'Enola Gay'.
No, how could he as Japan did not have them!
They attacked Japan with the Atomic Bomb and then they told them that they had to surrender or they would drop another atomic bomb. The Japanese refused to surrender and they dropped another one. This killed more than 200,000 Japanese. Finally Japan had surrendered.
Japan surrendered after 1 bomb was dropped in Hiroshima, and another one in Nagasaki.
Because even in the U.S. and Japan everyone hated the idea because an atomic bomb could kill everyone including children.
They had nothing they could do. The attack was a complete surprise.

It didn't. Japan existed long before the atomic bomb
