President Obama has an opportunity in Tuesday’s Oval Office address on Iraq to show that he has finally learned something about American security in the hard world of international geostrategy. Of course, if he did, it would mean abandoning much of what he advocated during his election campaign, reversing many of his most-prized policies since his inauguration, disappointing his leftist political base, and causing acute heartburn on Norway’s Nobel Peace Prize Committee. I’m not holding my breath. But if the president was blessed with a revelation during his summer vacation, perhaps he now understands what we have at stake in Iraq going forward.
