What does "through" mean?

[TNDemo]

People keep saying we have to stay in Iraq until we are through. What does through constitute?

[MrSlayer]

1. Until we install our puppet government and crush all resistance.

In a word: never.

2. until the oil runs out

n/t

3. Point: lastknowngood.

4. Until we have met our goal

What is our goal you might ask? I think it is as vague as the reasons for going to Iraq.
If you don't know what the goal is, then how do you know if you have met it?

added:
Until there are no more Terrorists of Mass Destruction.

5. "Through" means, in this instance...

When the "Status of Force Agreement" (SOFA) expires, the one to be executed with the puppet regime we put in place on June 30 (and who can name the last SOFA that was allowed to expire -- besides Saudi Arabia, of course?). After all, what do you think we're fighting for? Why, Dominion and militaristic hegemony, of course! We ring the Caspian Basin with bases during Afghanistan; and Haliburton is building 4 major bases in Iraq. Better to control the future flow of gas and oils, my fellow useless eaters and cannon fodder! Sweet Empire!! Bwahahahaha!!!

Watching Bush's head spin in a cheap imitation of Linda Blair in The Exorcist, out spewed forth a projectiling vomit of words. These words...

The transition to sovereignty also requires an atmosphere of security, and our coalition is working to provide that security...As we've made clear all along, our commitment to the success and security of Iraq will not end on June 30th. On July 1st and beyond, our reconstruction assistance will continue and our military commitment will continue...In terms of how long we'll be there, as long as necessary, and not one day more. The Iraqi people need us there to help with security. They need us there to fight off these, you know, violent few, who are doing everything they can to resist the advance of freedom. And I mentioned who they are...Once we transfer sovereignty, we'll enter into a security agreement with the government to which we pass sovereignty, the entity to which we pass sovereignty. And we'll need to be there for a while.

As Chalmers Johnson warns, "Plan your outs now, while it's still possible. Get a second passport; buy that condo in Vancouver!" The Sorrows of Empire will befall us.

(On edit: Changed "Security of force..." to "Status of force...")

6. You Sir, are a God in my eyes

Thank you for mentioning the Status of Forces Agreement.

I suspect that you and I are the only ones who noticed. They're setting up a permanent military presence in Iraq, and no one even notices.
