Because trump is going to end this war one way or another. Russia is now on a very short deadline and is throwing whatever they can to gain whatever land they can. After trump decides to do his thing, the lines will be frozen, for better or worse. Whatever deal ends up being written has to take that into account.
Trump will try giving Ukrainian land to Russia and Zelensky won’t go for it. End of story.
if that’ll be the case, i really hope that us won’t back out from giving them supplies
