Wrong.
The violence is to prevent the Iraqis from coming up with a stable government, and it's doing a pretty good job. If you didn't have your leftist blinders on, you would realize from the targets and the tactics that the insurgency is not about getting Americans to leave, it's about preventing Iraq from becoming a democratic country.
Peel loose from the agenda for five minutes, and look at what the terrorists over there are actually DOING.
