Trump Economic Jihad against America?

Building an economic wall round America to keep competition out is assinine economic illiteracy,economic chauvinism,waving a white flag and cowering in a protectionist bunker,an act of national suicide. Maybe the judges will rule that it is unconstitutional? If not the repercussions for the US could well be greater than 9/11 but all the worse in that the economic jihad will have been self inflicted.
