That particular letter is directed primarily towards a dislike for the President.
The letters that I receive from my friends speak primarily towards what is taking place in Iraq and the rapport with the Iraqi people. Some have made negative remarks about the President...usually the sons of my friends that are serving...and are on their first enlistment. All of my friends are career soldiers...other than some of their sons...and career soldiers...for the most part...are not into speaking out against their superiors which includes the President.
