Do you find it amazing US politicians like GWB can get away with war crimes that killed millions?

No, General George S. Patton was briefly removed from all command in 1943 for slapping a shell-shocked soldier in Italy and General MacArthur was removed in 1951 during the Korean War for trying to take his matters into his own hands like trying to nuke China without the President's approval. Get away with war crimes?

Probably yeah, only on the winning side or good guy side. Most Nazi and Japanese generals and admirals were charged for war crimes committed during World War II.

In America, UCMJ applies to you whether you're a private or a general. Most other countries have similar laws for their forces. Like anything else, what you get away with depends on what you are caught doing.

Can't prosecute someone for a crime when they aren't caught in the act. You also have to consider what is actually a war crime, versus what some random person or group claims is a war crime. People claim that the so-called "Collateral Murder" video was a war crime, when in reality it was a case of mistaken identity.

While it was questionable for the pilots to crack jokes, it was not illegal and they legitimately thought that they were firing on insurgents.

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.
