The MAGA/GOP belief is that Trump probably has a deal in place with Iran [View all]

that he will announce later today, and the absolutely insane bluster is at worst a bit of face saving, or (for the MAGAs) politicking, to say that he terrified them into submission.

That's basically the line that's being spread on neutral boards.

I do think there's a non-zero chance that this is accurate, since Trump seems to have gone way out on a limb here. I also think there's a chance he has absolutely lost the plot.
