what actually happened last night? was an agreement reached? is this the end of the war?
there is some real possibility that trump might decide it's not worth it and just sail off, but that's not what happened. what happened was that donald trump decided, clearly delusionally but nonetheless, that iran's counter-offer demonstrated he has a business partner in iran to make a deal with. that's what he said, and you should believe him. therefore, he doesn't need to blow them up, because he succeeded in bringing them to the table.
yes, they were at the table before this started. trump doesn't see that. he blocks that part out.
conservatives like to criticize liberals for wishful thinking, and that's the right way to understand donald trump. trump is demonstrating something conservatives call confirmation basis. the liberal analog to this is the suspension of disbelief, but trump is a liberal and not a conservative, and the conservative critique is more correct. trump sees what he wants to see, not things as they actually are.
trump legitimately believes he will negotiate a deal with iran that gives america what it wants, in exchange for what it doesn't care about. that's what happened, because that's what trump wanted to happen - he wanted his threats to force iran to negotiate, and he is seeing what he wants to see, rather than what is.
it's not clear how long these negotiations will need to fail before trump gets bored with them and it's not clear how he will react when he does, but he very well may just sail off, which is the worst outcome possible. but he did it in afghanistan, and he didn't learn from what happened.
so, the media is going to have all kinds of stupid analyses and they will mostly be wrong.
trump wants a deal and he grasped on pure magical thinking to prove himself right and give himself more time to make it. that's the reality of what happened.
