Despite the official US military withdrawal last December, American special forces "recently" returned to Iraq on a counter-terrorism mission, according to an American general in charge of weapons sales there. The mission was reported by the New York Times, in the fifteenth paragraph of a story about deepening sectarian divides.

The irony is that the US is protecting a pro-Iran Shiite regime in Baghdad against a Sunni-based insurgency while at the same time supporting a Sunni-led movement against the Iran-backed dictatorship in Syria. The Sunni rebellions are occurring in the vast Sunni region between northwestern Iraq and southern Syria where borders are porous.

During the Iraq War, many Iraqi insurgents from Anbar and Diyala provinces took sanctuary in Sunni areas of Syria. Now they are turning their weapons on two targets, the al-Malaki government in Baghdad and the Assad regime in Damascus.

The US is caught in the contradictions of proxy wars, favoring Iran’s ally in Iraq while trying to displace Iran’s proxy in Syria.

The lethal complication of the US Iraq policy is a military withdrawal that was propelled by political pressure from public opinion in the US even as the war could not be won on the battlefield. Military "redeployment", as the scenario is described, is a general’s nightmare. In the case of Vietnam, a "decent interval" was supposedly arranged by the Nixon administration to create the appearance of an orderly American withdrawal. During the same "interval", Nixon massively escalated his bombing campaign to no avail. Two years after the 1973 Paris peace accords, Saigon collapsed.

It is unlikely that the Maliki regime will fall to Sunni insurgents in Iraq, if only because the Sunni population is approximately twenty percent of the population. However, the return of US Special Forces is not likely to restore Iraqi stability, and they may become trapped in crossfire as the sectarian tensions deepen. The real lesson may be for Afghanistan, where another unwinnable, unaffordable war in support of an unpopular regime is stumbling towards 2014.
