wow. You say you have done "research", but half your facts are wrong.
-The Japanese did in fact have a navy AND an airforce. They used their airforce to attack Pearl Harbor, so they obviously had one, and the War in the Pacific was fought almost completely with aircraft carriers, battleships, planes, and the occasional skirmish on an island. So the Japanese did in fact have an airforce as well as a navy.
-The Japanese were NOT terrified of the Russians coming to invade. In fact, the Japanese had no fear of ANY communist power. They had invaded, taken over, and expelled Mao Zedong and the Communist forces (for the time being) so Communism was not in any way a threat to them. Also, the Russians have not beaten the Japanese before, it is the other way around. The Japanese absolutely slaughtered the Russians in the Russo-Japanese War, which is one of the causes of World War I, but thats a completely different story.
-Near the end of the war in the Pacific Theater, the United States was faced with two options. End the war through an invasion of Japan and possibly get involved in a lengthy, costly, and unnecessary war over occupation of a foreign country, or end the war through the dropping of two atomic bombs on Hiroshima and Nagasaki. At the time, many high-ranking officials were in support of the bombing of Japan, as it seemed to be the lesser of two evils.
Next time get your facts straight before you present an argument about a topic as controversial and broad as this.
