You sure about all that? Hunger within German population was present, the red army (part of the Allies) was known for rapes, and Israel did not bomb to the extend Allies bombed Dresden, not even close. The civilian losses in WW2 were massive. The cities after WW2 were in ruins, and both sides (with exception of Paris) did not hesitate to bomb cities if there were military targets including military manufacturing facilities.
Yes war is ugly, but not every war is genocide, most of them are not.
