As I said in the piece, victory will be defined when people in that part of the World (not just Iraq), no longer believe their status in an other worldly theoretical existence is more important than the value the Um-ma (The world wide Muslim community) as a Religion/civilization/culture put on the actual importance of a physical life..

As to our presence in Iraq, Should we give it back? Or (& I think this a better MILITARY tactic), do we maintain an operational size army & complimentary Task Force Carrier Group in theater, to act to threats in that part of the world as they come to bare?(Think Post WWII Western Europe, Japan, or Korea..) Questions following up on your Logic..
 
No American companies profited from reconstruction efforts in those countries post conflict?
 How about business ventures in Western Europe, Japan, & Korea?
Following your reasoning we should just ignore the realities of foreign trade altogether; and thereby negate a need for a Navy, (which was the primary reason it was formed in the first place), to protect foreign American interests in the international capitalist market? 
Do you heat your house with that same self righteous empty headed dogma in the winter? Of course you don't ..
You probably even drive a car...  Something perhaps you should  consider giving up if you want your inane rhetoric to have any credibility..
 
We are a country with numerous foreign financial concerns that affect each citizen of this planet (not just this country) in terms of potential fallout if those interests are disrupted..
 Unilateral I think not.. that is to laugh.. 

The fact that so many other countries are choosing to try to fly below the radar with Islam by deflecting blame onto the canard of "American Hegemony" is an indicator of what the threat level really is..  

Appeasers don't want to admit we are at war with an Ideology.. An Ideology that has no boundaries.. What it does have is wellsprings that act as headwaters for the flow of Radical Islam & extremist Ideology..

It happens that most of those sources are all in that geographic proximity, so prudent military planning requires us to maintain a fore-boding troop presence..( a presence that will be maintained long after I am dead & scattered... I should think.. & I'm 42 & reasonably healthy)..

Not leaving troops means moving entire armies across oceans.. Aside from not being able to rapidly deploy if needed, it is supremely expensive to do & that is a financial reality that cannot be overlooked when demanding re-deployments of troops..

Which brings us to why we really invaded Iraq.. It was, politically the most expedient way to attain our ultimate military objective.. A large military presence in theater to help apply diplomatic pressure on Iran... (The military sometimes must be used as the point of the spear for diplomacy.. & That is a cold hard fact of history)..

 One of the few nation states that is openly flouting our policy on State sponsored terrorism (A policy that goes back a Generation by the way) is Iran.. Iran has been actively funding terrorism around the globe through a proxy force called "Hezbollah" since it's inception shortly after the Iranian Revolution in 1979..
 Though I'm sure a person of your apparently limited frame of reference never heard of Kenneth Timmerman he has an excellent book ("Countdown to Crisis" the impending nuclear showdown with Iran), about Iran's involvement In:
 pre- 9/11 terror
 Links to Al-Qa'ida
The scope of it's Nuclear potential &
The potential threat they pose to not only Israel but Europe..

Many suspect Al-Qa'ida is being given refuge by the Mullahs in Tehran and this past week irrefutable evidence was presented that Iran is aiding the insurgency in Iraq & Afghanistan..

If you allow your mind to think beyond the little box it currently finds itself trapped in, you may see the difference in the negotiating position we have today with Iran, as opposed to the limited options available to Jimmy Carter & Bill Clinton when it came to bargaining with the Iranians.. Who are currently the greatest threat to the stability of the world as this is written..

You may want to familiarize yourself with some of the mysticism that surrounds Shia Islam, their belief that it is a religious obligation to bring about "the end times" is not hyperbole & the fodder for Cocktail party jokes, (at least to them, believe me..)

 One can argue the semantics of why we invaded Iraq until
the cows come home: you however choose to ignore the reality that when they do they will be wired with an Improvised Explosive Devises..
 
I don't parrot anything by the way.. I am critical thinker & any opinion I have gleaned through the years has been formulated by the reading & research that I have dedicated myself to..

As to irrelevant WWII analogies----Look at chapter 1,  pg 1. of the book I mentioned..  Then ask yourself..
How wise it would have been to tell the rest of the world that the invasion of Italy was just a rouse to divert the attention away from the North Western shores of France?
