The question of the scene Trump is designing in the Middle East is less a question of whom he is pro or anti but, simply, whether he is building to last. Which parties does he expect to continue to act in ways he is assuming they will and setting them up to act, and why?
If he's just creating a kind of tableau to refer to for as long as necessary as a certified accomplishment, then he is building a sand castle. This would be squarely in the tradition of US political mediation in the region. In that case, everyone waits him out until they can go
about their business again. Certainly all the language coming from various voices within the administration, including Trump, indicates as much. The thing to look for, then, is which arrangements counter the public representations and which new and effective agencies are created.
And "new and effective agencies" would simply be sovereigns who could serve as guarantors for actions within and proceeding from a given territory. The measure of Trump's arrangements is whether he is enabling such sovereigns or, rather, the spread of transnational lawlessness.
