I think he is trying to save the country from dividing. But frankly, the world would be better off with a less powerful USA now. And while not everyone can be saved from a Trump fate, some can be.
A country in which the folks in the middle can pursue their vision doesn't need to apply to those along the oceans who want something quite different. And heck, once the middle discovers what it wants, I imagine they'll see sense pretty quickly.
