Having been over there in the "Triangle of death" there are 2 ways it can be fought. A. Destroy everything, napalm, WP and torch all structures, wreck the entire city, kill every living thing that exists, ==donkey's with bombs, suicide bombers, even the kid with the grenade. Put holes in every wall that stands, adn then once its a pile of rubble blow it up some more. Similiar to what we did in Fallujah. 3 weeks of constant bombs falling, just decimating everything that exists.... The good side to it is we kill the enemy, everything dies, and we stop getting attacked. Troops are a plenty and the numbers are at all time highs. The downside? The bleeding heart peace activists claim that its killing innocent people, and call everyone executioners... Troops are threatened with court martial, and everyone gets screwed.
The other side is, let it exists how it is... pull the troops out or to their lowest levels and let the Iraq Security Forces handle the problem. Troops are at risk to be kidnapped because of such small unit sizes, and the risk of being "overrun" is very great. The insurgents/terrorists rule the land.... not only in spirit, but build a base of operations comparable to our US bases.... and continue their assaults/training. The US is blamed for not doing enough, and the peace activists still aren't happy because the sectarian killings go up.
Plan C. Pull everyone out, leave the country and let Iraq become the next terrorist disneyworld. All the terrorists that train there, can now come to the USA and continue their jihad. If we meet their demands of leaving, they call for something else -the destruction of israel. If they get that, then they demand that the US be destroyed as well. All apart of the cycle of life. These people are never happy, with good reason, its 120 degree's on a good day there... and they gotta live there. So in reality its always giong to continue. If this were a jungle war, it would be way worse... trust me.
