All true however you forgot to mention the simply fact that the Japanese had the philosophy "death before betraying the emperor!" if America had tried to step onto Japanese soil they would have to fight a war of attrition to the very last man.Manatee Slayer said:-The Japanese had virtually no Navy or Airforce to speak of.
-The Americans had blockaded Japan, meaning they couldn't get any imported recources, which is nearly everything. lol
-The japanese were terrified by the thought of the Russians coming, due to the fact they had lost to them before and that they would probably take over the country and install communism.
-Many high ranking officials were against the attack saying it was unnesisary and that the Japanese were ready to surrender anyway.
-Winston Churchill in his book ("The World At War") said that the bombs did not play any part in the defeat of Japan.
-The only reason people think that the bombs won the war in the Pacific is due to American Propagada.
Japan would simply of not surrendered til it had no other option and the entire Japanese people would throw themselves against the American invaders. America simply dropped the A bomb instead.
There was absolutely no other weapon even remotely like it before, it devastated an ENTIRE city, one bomb, if you had told the Japanese we can level your cities with one bomb they would of laughed in your face prior. Nearly everything was flattened and people were vaporized, before their minds had time to register the fact "we're screwed," then came the after effects, fallout, the black rain, blindness, it completely shell shocked the Japanese nation.
America then dropped a second one, which yes in my opinion was unnecessary, Japan surrendered immediately afterwards partly because America stated "tokyo next" to them. In my opinion the second bomb was used purely out of spite.
