Syndicated columnist Charles Krauthammer chides Barack Obama for his ineffective response to the Iranian crisis, essentially calling Obama a coward for his failure to act decisively as the Iranian people stand up to their tyrannical government.

From Krauthammer's latest column in Investor's Business Daily:

All hangs in the balance. The Khamenei regime is deciding whether to do a Tiananmen. And what side is the Obama administration taking? None. Except for the desire that this "vigorous debate" (press secretary Robert Gibbs' disgraceful euphemism) over election "irregularities" not stand in the way of U.S.-Iranian engagement on nuclear weapons.

Even from the narrow perspective of the nuclear issue, the administration's geopolitical calculus is absurd. There is zero chance that any such talks will denuclearize Iran. On Monday, Ahmadinejad declared yet again that the nuclear "file is shut, forever."

The only hope for a resolution of the nuclear question is regime change, which (if the successor regime were as moderate as pre-Khomeini Iran) might either stop the program, or make it manageable and nonthreatening.

That's our fundamental interest. And our fundamental values demand that we stand with demonstrators opposing a regime that is the antithesis of all we believe.

And where is our president? Afraid of "meddling." Afraid to take sides between the head-breaking, women-shackling exporters of terror — and the people in the street yearning to breathe free. This from a president who fancies himself the restorer of America's moral standing in the world.
