Because Trump can talk to Putin, Zelensky and others involved.
He’s lame duck.
Yes, of course, but if Biden gives Z-man the green light and then Trump not-yet-in-office talks him (Zelenskyy) out of it, Z-man’s own people on the right will take him (Z-man) out. I’m not talking about “Nazis” (though they would do so too), I’m talking about reasonably patriotic Ukrainians who have been convinced (mainly by Biden supporters and a lot of Europeans who support Ukraine) that Trump is Satan incarnate, Pooty’s tool, cannot possibly be trusted, etc. This is by far the largest bloc of people remaining in Ukrainian controlled territory. Then it’s up to Pooty to hold back, and he’d be under incredible pressure with such a group now in charge in Ukraine...
Unless Trump wins in a blowout and the Pubbies win the House and Senate too, there will also likely be election challenges to muddy the waters. How could Pooty be sure he doesn’t end up with Harris anyway?
