Trump knows he cannot bring manufacturing jobs back to the rust belt for a whole host of reasons like automation and the changing demands of the global economy.  But he can certainly give his supporters a target, like immigrants and Muslims, to blame for all their problems and that is what he is doing.  It is populist authoritarianism 101. 

The most important thing that we can do is keep protesting and make it uncomfortable as possible for the people who voted for Trump.  Don't let them, especially suburbanites who voted because of the Supreme Court or they didn't like Hillary, ignore what is happening.  Make sure they are reminded of people like the little refugee children who were harmed by Trump's orders.
