it is not a priori that one cannot ever ponder the thought of whether it was really worth it, per the above note. As many know, this thought was pondered in both Libya and Syria by those who lost limb and loved ones, and by those who might see their country falling apart. So it does depend on who’s doing the pondering, what they know, what they experienced, on what basis they are pondering, and where/how to actually utter it! To do so on CNN casually, considering all that can ben considered here, is the kind of liberal brutality that has historically damaged not just one life, but whole countries, and without being insulted, attacked, or even threatened (Iraq being a case in point). But that war was legally sanctioned domestically, and voted for in a nicely air-conditioned room, by people who dress well, and speak of liberal values, and might not mind if someone insulted their prophet or God.
