As to how people who are over there feel...read through this thread, I believe there are several who have been or are there.
My own contacts tell me that the vast majority understand the stakes and are willingly there...many volunteering fore multiple tours in country because of the importance...and almost universal anger at the MSM for not supporting the great good that is being done throughout Iraq in the vast majority of the country where the fighting is not occurring.
The link I provided in post #382 is from a soldier that is in Iraq for the third time as a VOLUNTEER. It is an excellent letter he wrote and shared.
