French diplomat Gérard Araud explained why Trump would easily give up on Ukraine:

- He doesn't like losing face. I am sure he would be prepared to give up support for Ukraine, but only if he can do so with as little loss of dignity as possible. I think this is exactly the stage he is currently in.

- But remember: during his first term, when he tried to negotiate with North Korea, it also started with an incredible "love story." Those letters! What happened between him and Kim Jong-un was truly incredible. Considering their personalities, it was really terrifying. But in the end, nothing was achieved. He backed down after mumbling a few words. He went home.

- Therefore, Trump could become frustrated at some point, because, as you know, his attention span is like that of a teenager. He gets bored easily, and may then say, "Well, I tried."
