Join the military and find out what the term "Rules of engagement" means before you go blaming the U.S. for "Blowing up thousands of innocent people" The U.S. Military takes upmost care to not kill civilians when conducting operations. Do civilians get killed? Of course they do, and it's a tradgedy. The difference is, we try to limit the amount of collateral damage and the terrorists try to kill as many civilians as possible, in fact their prime objective is the loss of civilian life.
The reason is, they hate us and our way of life, so by that way of thinking we can limit the attacks by making them like us. Yeah, I see that happening in the near future.
