Just read it. This is the basic reason I was against the war, because I feared it would turn into exactly such a mess. When you take over a country, and the people opposing you aren't really distinguished from the people you are trying to help -- that is, they both are coming pretty much from the general population, you are going to end up killing innocent people in the process, thereby making even more people hate you and willing to fight you, it can go on indefinitely with no resolution. Every person you kill has ten or so male relatives who just aren't going to care why he got blown up, but just that the Americans did it. I just can't see any way this is going to end well.
