Dov Zakheim calls for a minor American role:
What should Washington do now? Calling for Arab participation in military action is not enough; it will not get the U.S. off the military hook. The administration should make it clear that America's role will be limited to providing logistical and intelligence support, and enforcing a no-fly zone, while its allies attack Qaddafi's troops on the ground. The Arabs could do this, or the British, or the French, or some combination of all three and of others who wish to join in. At most, the U.S. should take out Libya's air defenses, which stand in the way of an effective no-fly zone. Even that operation could be conducted by the NATO allies.
Unless the administration specifies exactly what it is prepared to do, and not prepared to do, it will get called upon to do more than it should.
Here's hoping we play as limited a role as possible. But one fears that the military superiority of the US will drag us further in.
