How is fighting in Iraq defending civil liberties at home? I've heard a lot of talk about "defending our freedom", but there really is no threat in Iraq to any of the Bill of Rights in the United States, nor was there when Saddam Hussein was in power beforehand.
This same line was used for Vietnam as well and it never proved true, though we lost Vietnam.
The least courtesy someone could provide is telling kids why they are both killing and possibly dying, being maimed, or otherwise being physically or psychologically injured with an honest statement.
I don't believe it has anything to do with "defending freedom at home." Again, that same crap was fed to kids in Vietnam and it never came to be. If anything, Nixon stole freedom while they were over there.
