As I predicted/observed, the world has figured out how to deal with Trump: make promises about things you are already doing or can't do at all, and Trump laps it up because he seems to assume that if not for him, we'd all be living in caves.
So Canada got him to pull back the fentanyl tariffs by doing what they were already doing. Mexico actually scaled back its commitment and sold it to Trump as a concession (because he had no idea how much Mexico helps). The EU, in his first term, agreed to buy a bunch of LNG that it had no authority to buy and of course did not buy.
To get what you want from Trump, all you have to do is describe what you're already doing, tell him it's because of his great leadership, and maybe there's a few other things he could do . . .
