"Average cost per atomic device/bomb: $5 billion" (Debate on the pros and cons of dropping the atomic bomb on Japan)

By 1949, the Soviet Union had exploded and tested its first atomic bomb. (The Cold War Museum) So why the FREAK.. would we waste that much money on a scare tactic that may not work. Plus it could just encourage the Japanese to make one of there own.

What about the innocent civilians that were killed at Pearl Harbor. Remember the Japanese brought it on themselves. "A total of 2,335 U.S. servicemen were killed and 1,143 were wounded. Sixty-eight civilians were also killed and 35 were wounded." (history1900s.about.com/od/Pearl-Harbor/ a/Pearl-Harbor-Facts.htm)

The Japanese should have thought of fact that they had no allies when bombing Pearl harbor.The Japanese did not think about "immoral" when they made many American soldiers march to death and starve them and torture them.

"In the light of the sneak attack on Pearl Harbor, the "Bataan Death," and the torture and execution of Allied prisoners, no Japanese leader can dare accuse us of immoral behavior." Said by a legitimate source

There is no text based evidence for your claim. "...no Japanese leader can dare accuse us immoral behavior." This was said by the person who said this.

"Failure to make a military demonstration of the new bombs may make the war longer and expensive in humans lives..." Letter from Author Compton to Secretary of war Henry Stim son,June 15,1945.

"This is a war of extermination the Japanese militarists have made it that way."

Many American life's would have been lost also, the Japanese showed no mercy so in doing so the bombing was necessary.
