In a recent interview with Jan Frel of AlterNet, Noam Chomsky said:
I think that sooner or later the white working-class constituency will recognize, and in fact, much of the rural population will come to recognize, that the [Trump] promises are built on sand. There is nothing there.-RW
And then what happens becomes significant. In order to maintain his popularity, the Trump administration will have to try to find some means of rallying the support and changing the discourse from the policies that they are carrying out, which are basically a wrecking ball to something else. Maybe scapegoating, saying, "Well, I'm sorry, I can't bring your jobs back because these bad people are preventing it." And the typical scapegoating goes to vulnerable people: immigrants, terrorists, Muslims and elitists, whoever it may be. And that can turn out to be very ugly.
I think that we shouldn't put aside the possibility that there would be some kind of staged or alleged terrorist act, which can change the country instantly.
