Since you seem to consider yourself an expert please enlighten us as to just what "rules of war" our terrorist enemy is willing to abide by. Seems to me that you are only in favor of rules that don't apply to you.
I'm in favor of rules that apply to civilized human beings, which you are uninterested in being one of, especially when others aren't, or times get tough, or you feel threatened, which means you actually have no principles worthy of respect, none at all.
You are the kind that is moral or decent only when others are. If you think that puts you at a disadvantage, you toss your supposed "values" aside and act just as bad, or worse, than they are. That's not morality, that's nothin', and totally unworthy of respect.
