I will give Trump credit for pulling his aides back from the brink of war with Iran (though he was they guy who brought in these idiots. Like he didn't know who Bolton is...) and trust that it isn't only a matter of timing, as in not close enough to elections.
I'll also hope that reports that Trump's ultimate goal of repackaging a "renegotiated" Iran deal as "New and Improved!" and taking credit for it are true. That was a good deal, for the US, Iran, the world. We should be keeping it, one way or another.
