Not gonna comment about what's next, but it might not have been a good move for Trump to state that he believed a deal was at hand...
They are playing for time again just like always. They never intend to deal at all. Business as usual which is no deal at all. They just don’t make deals with infidels and the more you persecute them the better they like it and the more convinced they are they are doing the right thing. You can’t beat them into submission so you just have to kill them or live with what they do.
Trump saying a deal is at hand just gives them encouragement to keep going. They some how attach that to leverage in their favor.
I have said here many times what an old friend with Esso said, “Persians are crazy.”
A deal could be done, but it’s important to understand that a negotiation is 2 ways. FR might want to spend time imagining what Iran would demand, and that the US could agree to.
The reverse is just chest beating and not the path to guessing what is in the negotiations.
