Trump is currently playing the role of “mediator”, but he's a mediator with a perferential side, which is Russia.

It seems that the game has changed because Britain was the only country to seriously consider sending troops to Ukraine... because no European country has done so to date... Now they're going to arm themselves to the teeth... This is going to be the big “turning point” in this war, in my opinion. Let's wait for the scenes in the next chapters.
