I wasn't in favor of invading Iraq just as I wasn't in favor of going to Viet Nam. In the case of Nam we could have ended all that misery easily but our fighting men and women were hindered my various rules and edicts coming from our own leadership. For the record I served in that era but was stateside. The end result of both military operations were ill conceived and ended badly with tens of thousands of American troop deaths. Nation building doesn't work but our leadership never seem to get that concept.
