Another Iran?

Andrew Exum strikes a sour note:

Before the Afghan elections, every assessment you could read and every opinion you could solicit from policy-makers was the same: the worst outcome of the Afghan elections would be one that, in either the first or second round of voting, delivered the election to Hamid Karzai with a narrow margin of victory amidst wide-spread allegations of corruption and ballot box-stuffing. The overwhelming fear was of "another Iran" -- only with our fingerprints all over it. The worst-case scenario now appears to have been realized.

At what point in the history of occupying Afghanistan has the worst case not been realized?
