The fact you said "preferably out the army" means you were conceding that this was not a variable you considered crucial to your theory.

Furthermore, there is more evidence to rebut your theory that the soldier's are lying:

USAToday and the the Wall St. Journal are reporting that soldiers are re-enlisting at greater rates than targeted and are optimistic about chances for success in Iraq.

If, as you claimed, the soliders are lying about their feelings because they are still on active duty, then they would not re-enlist. They would stay home, attack the war and attack the president. The fact that they are re-enlisting would, conversely, tend to indicate they are telling the truth about their optimism for Iraq.
