Information War: Marine in Fallujah

They believe that things are progressively getting worse and think that our forces should just pick up and leave.
They do all this under the pretense that they are supporting the troops. However, what they are really doing is using our lives and the issue of our safety and well-being as a means to achieve a political end….

As a matter of fact, I assert with a considerable degree of confidence that their efforts make our already difficult job even more difficult. I’ll go so far as to say that their rallies and protests cost more and more servicemen their lives and limbs every day….

This marine doesn't just say that without giving an exact example of how it works to damage their effort and kills Marines:

The people of Iraq see when our country is divided. When they see rallies to “Bring The Troops Home,” they see that as a sign that we will end our efforts prematurely.

Furthermore, they know that the insurgents will not end their efforts early. That leads them to the conclusion that when we leave, the insurgents will still be there. Therefore, if they help us, their lives and the lives of their loved ones will be in great jeopardy the minute we leave — if we don’t finish the job
