Everyone drops bombs in war... that doesn't make you a war criminal... some people torture... and they are usually called war criminals...
It has a lot to do with the false pretenses under which the Iraq War was started. That said, I still wouldn't call Bush a war criminal, just a misguided jerk. The allies killed millions of civilians in World War Two, but those are not "war crimes" either.
Just a grim reminder of how horrible war can be.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
