The Obama administration has yet to find its footing amidst the political tremblings across the Middle East. And Washington's reactions have been inconsistent.
When the Green Movement called for democracy in Iran, Obama signalled to the Tehran leadership that he would stand aloof.
Yet when long-standing American ally Hosni Mubarak of Egypt faced demonstrations, Obama quickly called for him to resign. Servility toward enemies and abandonment of friends seems to be the watchword for American foreign policy: except of course with that old friend Saudi Arabia, whose invasion of Bahrain evoked no US protests.
