Grudging Benefit of the Doubt -- Obama and Iran - UPDATED

Much as I'd like to join the chorus of those excoriating Obama for not unequivocally backing the Iranian protesters, I can't quite. Why give the mullahs a more credible opportunity to blame the unrest on outside agitators? If Obama actually had guts and a devotion to American-style democracy, wouldn't it be wise for him to walk pretty much the line he's walking?

UPDATE: OK, they're blaming us anyway, and Mousavi's spokesman didn't ask us to keep out of it. Time to man up, Pres-boy!
