First of all I want to say - anyone who believes Obozo's skills in diplomacy will be able to stop Iran from getting nukes is an asshole and hasn't been watching him get his ass handed to him in virtually international negotiation . My feeling is Obozo doesn't consider Iran an existential threat, or a threat to America, period, if Iran does get nukes. While this may be foolish, we don't call him Obozo for nothing. In any case - he sees Iran getting nukes as a problem for countries in that region, but none more than a problem for Israel - a country who he has contempt for. I don't think he's being outmatched or outmaneuvered by Iran. I believe he wants them to have nukes so the power balance shifts in the Middle East and Israel becomes threatened and maybe destroyed.
