They got their wish...

US hawks rooting for hardline Iranian candidate was from the "Financial Times".

US "hawks", he said, had a bizarre preference for Mahmoud Ahmadi-Nejad, a fundamentalist and hardliner, over Akbar Hashemi Rafsanjani, the former president who sought to establish his more pragmatic credentials in part by making overtures to the US during his election campaign.
The US hawks also believe that a convergence of hardliners in Iran with the victory of Mr Ahmadi-Nejad is more likely to precipitate the collapse of the Islamic regime through popular unrest than the "Chinese model" of social pacification likely to be embraced by Mr Rafsanjani.

So they backed the right horse - their man won. But "collapse?" A big gamble - or maybe his election will set in motion some reasons to invade.
