One good objective point that any reasonable person would agree with is the way he has gone after American hostages. He is really, really good at getting our people back. Like most recently with the Kim summit, he got our hostages on good faith and then canceled that shit lol. He’s ruthless and it’s hilarious, the summit is back on of course but even if it wasn’t, we still got our people back. He didn’t have to trade terrorist leaders or fly billion dollar pallets (of different untraceable currencies) to secret drop spots like Obama did. He’s good at negotiations because people think he’s crazy, he’s playing those people like a fiddle.
I would not consider that a good thing. You get something then you cancel a agreement. What it does is make it look like the American president cannot be trusted. When your word is your bond, why would anyone trust you after that. Now when you go into Negotiations, they will bring up that very incident, show where you have either lied or been deceitful and thus ask for the world. There is nothing really smart about how he goes about negotiations. First he threatens then he wants to go to the table believe these countries must deal the way he sees fit. The problem is that they will all just sit tight and see what happens in 2 years or 6. Also, since we do not know, how things will go with these negotiations, you cannot really give him any credit until the ink drys on the agreement.
