A couple of bus bombs isn't going to stop much. Doesn't in Israel. I've lived with my relatives coming into that kind of danger DAILY. It's part of life, and you should be embarassed that you're starting to think this now, as opposed to all your life.
Then again, we all should, because there are bloody wars, civil and otherwise, that we ignore every day. Serves us right (not that anyone should die, mind you) that we cannot ignore it now.
