Is the Iraq War helping the terrorists?

More than anything, the terrorists are engaging in a psychological war. What sense does it make to engage them in a conventional war when they choose the time and place of their attack and then disappear? This is the definition of guerilla warfare and psychological warfare. Each time a soldier of ours gets killed or maimed, the enemy is inflicting damage (especially psychological damage) to us without receiving any. Even if it ends in a stalemate, we still lose because the enemy is so much smaller than us. It's a much bigger victory for them. This war needed to be fought in the shadows using the CIA and covert techniques - not with troops on the ground. Every day, we are paying a huge price in morale, money, world opinion, military resources, and human lives. I fear we are creating more terrorists with our policy of preemptive strike and invasion. We have a lot more to lose because our enemies will prove that the 'Great Satan' can be handed a defeat.
