Faculty Director of the Undergraduate College of Global Studies at Stony Brook University in New York, Professor Michael Schwartz, has written extensively on insurgency and the US Empire.
He pointed out to Truthout that President Obama's "... actions have made it very clear that he is unwilling to sacrifice the 50,000-strong strike force, even while he has also said he would abide by the SOFA and remove all troops from Iraq by the end of 2011. In the meantime, Gates and various generals have released hedging statements or trial balloons saying that the 2011 deadline might be impractical and that various types of forces might stay longer, either to provide air power, to continue training the Iraq military, or to protect Iraq from invasion. Any or all of these could translate into the maintenance of the 50k strike force as well as the five 'enduring bases.'"
That the Obama administration intends to maintain a significant military presence in Iraq after 2011 is obvious from its continued insistence that in Iraq "democracy" must be guaranteed.
Schwartz explained:
In Washington speak this means that the government of Iraq must be an ally of the United States, a condition that has been iterated and reiterated by all factions (GOP and Democrat) in Washington, since the original invasion. Given the increasing unwillingness of the Maliki administration to follow US dictates (for example, on oil contracts, on relations with Iran, and on relations with Anbar and other Sunni provinces), the removal of troops would allow Maliki even more leeway to pursue policies unacceptable to Washington. Thus, even if Maliki succeeds himself in the Premiership, the US may need troops to keep the pressure on him. If he does not succeed himself, then the likely alternate choices are far more explicit in their antagonism to integration of Iraq into the US sphere of interest ... the Obama administration would then be left with the unacceptable prospect that withdrawal would result in Iraq adopting a posture not unlike Iran's with regard to US presence and influence in the Middle East.
His grim conclusion:
All in all, there are myriad signs that withdrawal of US troops might result in Iraq breaking free from US influence and/or deprive the United States of the strong military presence in that part of the Middle East that both Bush and Obama advocated and have struggled to establish. Until I see some sign that the five bases are going to be dismantled, I will continue to believe that the US will find some reason - with or without the consent of the Iraqi government - to maintain a very large (on the order of 50k) military force there.
Expanding the Base
The US embassy in Iraq, already the largest diplomatic compound on the planet and the size of the Vatican City, is now likely to be doubled in size. Robert Ford, the deputy chief of mission in Baghdad, told reporters in January, "If Congress gives us the money we are asking for, this embassy is going to be twice the size it is now. It's not going down, it's getting bigger."
In 2005, The Washington Post reported:
An even more expensive airfield renovation is underway in Iraq at the Balad air base, a hub for US military logistics, where for $124 million the Air Force is building additional ramp space for cargo planes and helicopters. And farther south, in Qatar, a state-of-the-art, 104,000-square-foot air operations center for monitoring US aircraft in the Middle East, Central Asia and Africa is taking shape in the form of a giant concrete bunker ... the US military has more than $1.2 billion in projects either underway or planned in the Central Command region - an expansion plan that US commanders say is necessary both to sustain operations in Iraq and Afghanistan and to provide for a long-term presence in the area.
Lt. Gen. Walter E. Buchanan III, who oversees Central Command's air operations pointed out, "As the ground force shrinks, we'll need the air to be able to put a presence in parts of the country where we don't have soldiers, to keep eyes out where we don't have soldiers on the ground."
In 2007 in a piece titled "US Builds Air base in Iraq for the Long Haul" NPR reported, "The US military base in Balad, about 60 miles north of Baghdad, is rapidly becoming one of the largest American military installations on foreign soil ... The base is one giant construction project, with new roads, sidewalks, and structures going up across this 16-square-mile fortress in the center of Iraq, all with an eye toward the next few decades."
It is so big that, "There is a regular bus service within its perimeter to ferry around the tens of thousands of troops and contractors who live here. And the services are commensurate with the size of the population. The Subway sandwich chain is one of several US chains with a foothold here. There are two base exchanges that are about as large as a Target or K-Mart. Consumer items from laptop computers to flat-screen TV's to Harley Davidson motorcycles are available for purchase."
The report added, "Several senior military officials have privately described Balad Air Base, and a few other large installations in Iraq, as future bases of operation for the US military." The term used is "lily pad," a description of the military jumping from base to base without ever touching the ground in between.
In September 2009 The New York Times reported about Balad:
