My requirements for war
Before we go in I would like to see the following things:
UN sanction (implies no security council vetos).
A coalition of several allied countries directly involved.
The blessing of Saudi Arabia, Turkey, and Egypt.
Some kind of assurances about what post-Saddam Iraq looks like. Or failing that, I'd probably settle for a sign that the administration has some kind of plan.
If we can't get those I would prefer to go the inspection/sanction path.
