Hiroshima and Nagasaki

With the atomic bombing of Hiroshima and Nagasaki, the U.S. DIRECTLY targeted civilians.  They also directly targeted civilians with the firebombing of Tokyo and Dresden.  The Japanese and German GOVERNMENTS committed many atrocities, but that in no way makes it moral or right for the U.S. to murder civilians in those countries.

You can make all the arguments you want about how murdering these civilians brought an early end to the war.  This does not change the fact that civilian men, women, and children were murdered.  When other people do this, we call them terrorists.  That label applies equally here.

well, seeing how the US Congress gave the President full power to fight WWII and that there's no law defining just or unjust war and that self-defense in an unquestionable national right and that those two cities were industrial and heavily involved in helping wartime japan and that the emperor had consistently refused to surrender and that after the bombings, japan not only made an unconditional surrender but welcomed american occupation...

i'd say you have a pretty weak case.
