No, I expect them to fear a sword hanging over their head. Nothing else will work with them and you know it as well as I do.
Thus, they have to respect the threat. They have to know that the POTUS will have the will to do bring down the hammer rather than just give them goodies and trust them that they aren't breaking the rules by having an international organization with no real power oversee them. Further, when surveillance shows noncompliance (such as happened under JCPOA), then that leader must act.

It is one of the reasons that I have voted Republican in presidential elections. It is why you should too. Otherwise, we will have a party change and not only have someone that they do not fear, but someone that they will be able to con into getting reparations.
