the US responds with full force. Germany and Japan were destroyed because they attacked us. The Taliban were destroyed because of 9/11. Saddam's regime was destroyed to make sure he would'nt attack us. People would have to think hard before attacking us.
BTW 52 million people were killed in WW2..how many do you think the US was responsible for?
The US is very new to world history. Nation destroying goes all the way to the bible, which is full of it.
