As someone who favored the invasion of Iraq without UN Security Council authorization, and who stands by this position to this day, the course change I propose here comes after much reflection and with considerable reluctance. My reluctance stems from the fact that, should this proposal be implemented, it would mean the abandonment of what has long been the Bush Administration’s primary objective: to establish a stable, democratic Iraq. This admirable goal would give way to another goal espoused with equal frequency by the Administration: to contain the spread of international terrorism by al-Qaeda and other jihadi groups. In simple terms, the proposal gives priority to realpolitik over idealism.

Despite a beefed-up security effort by the Iraqi government, a record 3,400 Iraqi civilians were killed last month. Among others, senior American military officials have opined that sectarian violence has resulted in a state of near, if not actual, civil war. I see nothing on the horizon suggestive of an easing of tensions between the Shi’a and the Sunnis. More likely than not, the situation will further deteriorate.

Given American public opinion, the one action that could conceivably turn things around—a substantial increase in our force level—is absolutely, positively out of the question. Even if a decision to boost the number of boots on the ground were deferred until after this fall’s elections, it would be political suicide for the Republicans—in 2008.

It’s nonsensical to throw good lives after bad—and good money after bad—by having our soldiers and marines caught in the crossfire between between two Islamic sects that have hated each other for more than thirteen centuries. It didn’t have to turn out this way: never before has this mutual enmity raised its ugly head in Iraq. The Administration’s mistakes are responsible for it. However, throwing dirt in Bush’s face and using the benefits of hindsight to show how things could have been done better aren’t my purposes here.

We are where we are, and I believe that the American national interest can best be served by redeploying our troops to Iraq’s borders with Saudi Arabia, Iran, and Syria to limit the ingress and egress of current and future terrorists. Iraq’s perimeter should become a no-fly zone. Our navy can guard Iraq’s small coastline.

The quarantine of Iraq would have benefits in addition to limiting the flow of terrorists:

  • Having our troops stationed on the borders of Iran and, less importantly, Syria would send the message to the Tehran theocrats and the Damascus thugs that a diminution of our resolve shouldn’t be inferred from the change in our deployment policy.

  • Given Iran’s nuclear ambitions, having American forces on its borders would introduce uncertainty as to our reaction should its program reach the point of no return. If Iran were to attack, our presence would act as a tripwire for the use of airpower, as during the Cold War.

  • Having our troops on their border would reassure the Saudis by decreasing the likelihood that the Iranians will attack Saudi oilfields. Most of the oilfields are located in the predominantly Shi’a portion of the Kingdom, which is only a missile lob across the Persian Gulf.

  • Because the proposed redeployment is directly related to our national interest, it could be more readily explained to Americans, more of whom would support our presence in Iraq. National unity would increase; partisanship would decline.
