You know, I don't believe he miscalculated anything because he's never calculated anything.
His 25+ year history as a public figure has demonstrated exhaustively that he doesn't consider the consequences of his actions as a matter of course in any scenario under any circumstance.
It's why his politics are irrelevant -- he's unfit to govern, unfit to lead. Period, end of.
I certainly agree with your last sentence.
I just think he thought he could make friends with Putin by siding with him and everyone would be talking about how great he was for sorting NK, NATO and Putin out and he’d return to the US and get one big pat on the back. That’s how the scenario played out in his tiny brain.
What he’s massively underestimated is how much the US public and even both major political parties, believe in the justice system and intelligence agencies, and its fucked him this week, massively.
He has, in a way, been treasonous in how he’s conducted himself.
