Your post beautifully, if perhaps not intentionally illustrates the siliness of left-wingers when they always cry about the limits of "American military power." If were to fight a war again like Churchill and Eisenhower fought in WWII, the Iraq war and the Afghanistan War would have been over in months.
It's tough to to win at anything win you're the only one playing by the rules. Churchill understood this. The MOAB is the most lethal conventional weapon ever constructed, yet it has been deployed in actual combat, I believe, only 2 or three times. Churchill would have started dropping them and not stopped until A) there was an unconditional surrender, or B) He ran out of MOAB's to drop. Oh how time has changed things.
Yes I would drop 100 just to send a message and work out the kinks. Then Id get down to some serious bombing. We make it so hard these days when its really quite obvious and easy.
