I thought he had a plan or some deal with Putin. This sounds like something Biden would say.
There is no way to "save" Ukraine. Trump got stuck with idiot Biden's problem. I suspect Trump wants to keep Ukraine on the back burner until Senate confirms his Cabinet. So for now, he's merely repeating DC deep-state nonsense about sanctions, Russian casualties, etc... .
After that, I expect him to wash his hands entirely of Ukraine, and tell Europe it's their problem - which they will fumble. That's when Ukraine Govt collapses to much whining and wailing in DC.
IMHO
