Considering Iran’s policy on homosexuality is “Don’t Tell or Don’t Live”, I think having Obama shout “I LOVE YOU!! YOU’RE ADORABLE!!” at Ahmadinejad would creep him out sufficiently to make him rethink his nuclear program.
Can’t be any less effective than sanctions.

Might be a good way to get rid of him. Start a rumor…’Ahmadinejad is queer’…and pass it on. Next thing you know (after a fair, and impartial Islamic trial) he’s on his way to the holy chopping block. Problem solved.
