Bro... Ukraine has been degraded since last year to the point where I have concerns about their front collapsing.
US and EU support was trickled to get Ukraine cornered... We can argue over reasons but this-where we are at.
With Ukraine being this soft, it is gonna be hard to them to argue much of anything.
Kellogg can't ain't there to rep Ukraine, he is there to cut a deal that benefits US. He will do just that, Ukraine is just lucky from pure cold real politiks angle US hawks need Ukraine in a decent shape post peace deal.
So that's what will likely happen. Time will tell.
