so, if I can pursue your logic >>>once we determined that there were no WMD's and Iraq didn't have the capability to build WMD's it was adios<<<
would mean that
1 - the mad mullahs fury against the West, particularly the USA, would have dissipated and the WoT would have been over with only cleanup to be carried out in Afghanistan
2 - the suicide bombers coming into Iraq would be happily tending their sheep in SA, Syria, Yemen etc.
or, maybe
3 - we abandon all interests in the ME and withdraw all forces from Arab lands
So just where would we draw the line ???
