Throwing money and men at the problem is not a strategy, Joe. If it was, Vietnam would have been a cakewalk and the USSR would have pacified Afghanistan in no time at all.
The strategy now is working well. The insurgents/terrorists have been pushed back to the Syrian border, there are enough trained Iraqi troops now that this has been made possible. Last year we went on search and destroy missions, now we're doing clear and hold operations. Public opinion in Iraq for the insurgency is eroded w/ every suicide bomb going off in a mosque or market. In fact, there is now open warfare between Iraqi insurgents and Zarqawi's terrorists in many places.
There's more to military strategy than body counts, not that CNN et al would ever notice.
The insurgency a year ago controlled many towns in western Iraq, now they are reduced to a few backwater areas along the Syrian border, and those won't last much longer. The military situation of the insurgency is hopeless, they are putting their last resources (car bombs and other terrorist strikes of no military value) to try to win through propaganda (via the western media) what they can't win militarily. Thus, the increasingly desperate car bomb attacks against mosques, hotels, and markets.
Of course, this won't stop some US politicians from trying to snatch defeat from the jaws of victory...
