An Iranian nuclear deal?
The deal was reportedly brokered by Brazil, although the "tick-tock" hasn't really been written yet, so we don't know if Brazil really set it all up or whether Iran just gave them the credit to keep such a deal away from association with the US. (Any way this breaks is a huge "world stage" coup for up and coming Brazil.)
So far, it appears to be set up without consultation with the IAEA and, at least officially, without the US, so I really think we'll have to wait to see the details before a full judgment. Here's two early versions: AP and the NYTimes.
Aaahh, here it is. The BBC notes that, thus far, such a deal doesn't seem to inhibit Iran's enrichment processes and research.
