Victory in Iraq?

What is victory, winning, etc. in Iraq, or any place else for that matter? We didn't win in Korea (stalemate) and we didn't "win" in Vietnam so we can't use them as examples of "win". We did "win" during World War I and II. Winning those wars meant completely pulverizing the enemy and destroying their will to fight on. Winning against Japan was the most dramatic--we completely annihilated two cities--burnt them to a crisp. So what is the most likely scenario to winning in Iraq?
Since resentment is growing in Iraq against the U.S. and Britain it doesn't appear that we are winning hearts and minds very fast in that country; nor is it likely to occur at all. The gratitude we expected from removing Saddam was brief and is now forgotten. It appears we depended on that gratitude to "win". Now how do we win and declare victory? We can't fight all factions and hope to win. Siding with the irrational Shiites is a no win situation, so we are back to using the old tactic that the British used--pick a faction and let them rule. Sun Tzu would be proud! So if Muqtada Al-Sadr wants to give us trouble back the Sunnis. We certainly don't want the Iranians to take over by proxy, do we? We would then split the Muslim world and would be allied to half rather than be enemies with all. The Saudis are Sunnis, as well as the Syrians--and they are a little more rational in their dealings with the West. Israel is still left hanging however. How long can Israel hang on that is the big question? How long can the U.S. continue to support and subsidize Israel? So who is winning and what constitutes victory? No one has explained or defined either so far.
Winning in Iraq would mean that only one entity would rule over all the factions that now exist in Iraq and so far no plan has been implemented that would accomplish that. Tribal affiliations would have to be subordinate to the central government. Since those tribal affiliations have existed over hundreds of years I don't see how, in a short period of time, that they would be set aside merely to create a country that never existed in the first place.
Since the role of the U.S. has been prematurely diminished in favor of a so-called Iraqi sovereignty we gave up all hope of providing security that is necessary for the government to function and for us to "win" the peace. With such a mish-mash of bureaucratic confusion there is little hope of doing anything constructive. Win? Forget it, it will never happen.
