Lots of positives, for those who see Iran not developing nuclear weapons as a positive. Their enriched uranium will be destroyed and they will have to demonstrate a commitment to not building nuclear weapons, in return for money that will be good for the Iranian economy and for the Iranian people:
Technical talks on Iran's nuclear programme are expected to begin this week... while any sanctions relief or release of assets will depend on Iran meeting commitments under the deal.
"what the MOU does is set up a framework whereby the Iranians get the benefits of the bargain by meeting their obligations under the bargain," Vance said.
In "paragraph one" of the document it is outlined that Iran will commit itself to "regional peace and stability", Vance said, which he added included stopping the funding of "terrorist organisations".
"Most importantly, they're going to have a verifiable commitment to not building a nuclear weapon," Vance said.
The deal will extend a ceasefire for another 60 days, during which the sides will negotiate details of a final agreement.
Announcing the breakthrough on Sunday, Pakistan's Prime Minister Shehbaz Sharif, whose nation had been mediating, said it included "the immediate and permanent termination of military operations on all fronts, including in Lebanon".
The US officials said that while Lebanon was covered by the ceasefire framework, the withdrawal of Israeli forces from Lebanese territory was not a condition of the deal. Israel would retain the right to self defence, they added.
