After years of war, Ukraine is devastated, depopulated, and completely reliant on western cash, arms, and goodwill. Bizarrely, Zelenskyy thinks he holds all the cards.
He let Democrats and Euros convince him weapons, manpower, & money aren't important -- that moral authority is all. And that he's somehow more righteous than everyone else, including the taxpayers funding him.
In his mind, by insulting the U.S. -- in the White House no less -- that will somehow shame Trump into compliance. It's the Greta Thunberg model of geopolitics.
The right way to play this is to be damn near obsequious in his praise and thanksgiving to the American people, who have given him untold billions. Drop the short-man syndrome tirades and grievance. Read the room.
