I really don't see this happening. In his debate with Harris, Donald said when he's still president-elect he'll get the Russia-Ukraine war settled. "If I win, when I'm president-elect and what I'll do is I'll speak to one, I'll speak to the other, I'll get them together." Yeah, sounds like a plan.
Now he's saying the Russia-Ukraine situation is going to be very difficult. Actually, I think many of the world's leaders see Trump as more of a clown, not someone to take that seriously. In this video clip he looks like he's on something and can hardly get his words out.
