On what facts do you base the conclusion that their is a lack of armor, and the subsequent claim that as a result, problems in pacifying Fallujah have been exacerbated?
Their is a carrier task force in the gulf, and at the very least, hundreds and hundreds of M1A1 tanks in theatre.
Air power and tanks are for destroying things. If we wanted to, we could have turned the slums of a Fallujah into a smoking series of rubble piles and craters overnight.
Three AC130 gunships could accomplish the same thing, lobbing 105's around the clock.
You don't go about winning the "hearts and minds" of a people until they know they've been defeated. Which doesn't appear to be the case in Fullajah [sarcasm].
We need to convince the people of that city that we're the big dog on the block and then we can worry about winning there darn "hearts and minds" in my opinion.
