Who Is The Constituency?

The Trump Administration is currently pursuing two policies that make very little sense.

First, they are going to hire out the US military to support Saudi Arabia, because....?

Second, they are going to actively work to make the climate worse.

Which Americans are served by this?  Does the military want to get involved in another war in the Middle East?  Are American troops eager to return to that theater?

And who is served by interfering with California emissions rules? Car makers don't want it.  California doesn't want it.  It has zero effect on other states really.  I suppose it helps gas companies, because cars might get worse gas mileage.  But will car makers really go all-in on making gas guzzlers when all the global trends are going the other direction and any Democratic administration will reverse this ruling.

Who are they working for?

What is the goal here?
