We all Want the US out Iraq but...

I never was very clear on this, so what do you people think should the US get out of Iraq and if so what do you think will happen afterwards ?

Edit:
So the general idea based on Bilal's and mohanned's comments ( thanks for contributing) is that it would be better for them to leave Iraq and it will sort it's own mess out but that will never happen.
The way i see it is as someone who is living in Jordan I am against the United states cutting and running out of Iraq the same way it did in Vietnam, there needs to be a negotiated agreement with some international forces to take control from the united states and through all of that a deposition of the method of governance and renegotiation between the Iraqi sects that aim at maintaining the country as a single entity and at the same time allowing some Independent governance of the different areas. otherwise instead of a endemic warfare its going to be a pandemic warfare.

If they do leave, and yes mohanned it is the most likely scenario by 2009 if not earlier, and the situation in Iraq is not contained. that will mean trouble for the whole region that is far greater than what we are facing now. The country to take the majority of the damage due to that will be Jordan.
so if they cut and run out of, the killings in Iraq due to sectarian violence is bound to increase in order to secure power. Now those sects will establish ties with the neighboring countries in order for them to contain the carnage within Iraq in exchange for supplies. Or they might rely on the bases in their country.
Now the more you rely on American aid the more prone you are to a terrorist attack and the more refugees you take in the more prone that sectarian violence will resurges with the tensions rising between those refugees in their host country.
So it is a lose-lose situation either way, if you lean too much toward either side you are inviting violence.

Whose the country that is most willing to accept Iraqi refugees ?
So as it stands currently ironically although am totally against the war in Iraq, i feel its far better for the whole region if the United states stays there since it acts a buffer so far. The weird thing about Iraq that the violence is discriminatory, you are never too sure if it foreigners, liberators, terrorists, fanatics, sectarian or just blood lust. Some how reminds me of conflicts in Africa, Rwanda style.

see why that wasn't a comment :P
what do u guys think ?
ps. mohannad the US can't maintain the war in its current form neither economically or politically.
