I think a big obstacle is Trumping wanting Iran to give its enriched uranium to the US for storage. Europe, China, and Russia would be open to it being stored in their countries or Pakistan. Iran trusts these 3 countries more. Also, China and Russia are allies of Iran and can pressure it into an agreement.
