If you are fighting insurgents inside cities where enemy is in close proximity of children and women you can not damn reality and shoot to death whoever you suspect to be an enemy. That will always get you more enemies and endless war regardless of the noble cause that you may be pursuing.

What the soldiers are doing is mostly shielding their butts while they maintain their presence. They are not helping the invaded civilians if they are also killing scores of them every now and then while being unable to stop the insurgents who are doing the same thing.
