It is impossible to believe a denunciation of the regime by Obama will cause it to stay its hand if it believes its power is imperiled. But it is certain that if Obama denounces Tehran, those demonstrators will be portrayed as dupes and agents of America before and after they meet their fate.

If standing up and denouncing the Ayatollah and Ahmadinejad from 7,000 miles away is moral heroism, it is moral heroism at other people's expense.

One could assume that any country with a "supreme leader" whose power is handed down by God probably has a regime that doesn't care about the beating they'll take on Facebook forums.

Pray for the Iranian people, because it will take much more than a handful of martyrs and an endless stream of online flotsam to set them free.

However "right" open condemnation might be, would it be influential in a helpful direction, i.e. to settle matters without undue bloodshed with highly uncertain results? Wolfowitz, the master strategist of the Bush administration for the Middle East, argues a resounding yes. He points to the color revolutions of Eastern Europe in the late 1980s, and yes, there's something to this. But Soviet leader Mikhail Gorbachev was actually dismantling the Soviet empire-doing our work for us-and neither Ronald Reagan nor George H.W. Bush wanted to interfere with that process. Wolfowitz also cites the Philippines and the overthrow of Ferdinand Marcos. But of course, Washington had enormous influence with the Filipino security forces to back up our calls for democracy, which we totally lack in Iran. Wolfowitz fails to mention moral calls in the 1950s by John Foster Dulles and the C.I.A. for uprisings in Hungary and its neighbors. The result? Soviet armies crushed the revolutionaries, and we did nothing, as President Eisenhower had made clear was his position beforehand. And Wolfowitz doesn't mention H.W. Bush's urging the Shiites of southern Iraq to rebel against Saddam in the wake of the first Gulf War. This resulted in a Shiite rebellion and in Saddam's killing tens of thousands of those poor souls, while Washington did absolutely nothing. And what about Tiananmen? Would going to the moral mattresses have prevented the awful crackdown by the Chinese communist government? Not a chance. And look where we are today-with China as America's biggest holder of U.S. securities. Wolfowitz and his fellow neocons are well aware of these histories and historical complexities. So, their disregard of any fair-minded exposition of the issue suggests a hidden motive-the Krauthammer goal of confrontation and regime change.
