Do a google search on "Just War" for even more information and debate. This is not something new. I am just surprised that our most Christian and Holy President send by God above didn't seem to even think about this. This is not just a "christian' thing though although it was thought of by St. Augustine. Ethical people and non-christians consider this as well. Happy Reading!
