Ukraine was being excluded from the get go. It was going to be Trump and Putin making a deal, carving up the world as great men do.What that will mean is that some solution will be imposed by the real power-brokers, and they won't have to care a fig for what Zelensky thinks.
Who cares about these little powerless countries?
If Trump is this genius deal maker, then he ought to understand that both Ukraine and Russia need to get something from "the deal".He's just about cut himself completely out of any negotiations that are going to happen, and made it impossible for the US to include him.
And if he's a statesman then he can swallow his ego and bring both sides to the table.
