We have seen DJT tackle almost anything anywhere and do it successfully. Dealing with Russia and Ukraine is about as tough as it gets. Add in 50 other issues that our President is dealing with and I don't see how he does it all. Ukraine has always been a corrupt disaster. Z is about as corrupt as any non-elected leader can possibly be and it shows. Add in all the other variables and you have a giant cluster that if it were possible we would stay away from as far as we could get.
That may not be possible right now. Bearing in mind the above there is still only one leader who can sort out the morass that is the Ukraine and he's our President.
I have a hunch that Ukraine has a nuke no one knows the location of, and that’s why Russia stays bogged down with a ground war. Putin could lay waste to the entire Ukraine infrastructure in two days if he wanted. Either that or Russia wants Ukraine completely in tact.
