One of the Obama administration's contentions about Iran is that their diplomacy has succeeded in isolating Iran. But with Russia promising to follow through on their 2007 contract to sell surface to air missiles to Iran, China rejecting additional sanctions and states like India, Turkey, Brazil and Qatar engaging with the regime, it's difficult to take such a claim seriously.
This is ultimately why it's difficult to see how sanctions are going to stop Iran's nuclear program, much less change the regime.
