Donald Trump is not the only nationalist in American politics, only the man of the moment most comfortable with nationalistic posturing. Senator Bernie Sanders may be a socialist crackpot from Brooklyn, but he also denounces the liberalization of immigration as “open borders,” which he insists is “a Koch brothers proposal” and “a right-wing proposal, which say, essentially, there is no United States.” Barack Obama parrots every national socialist from Benito Mussolini to Hugo Chávez with his talk of “a new nationalism,” while Hillary Rodham Clinton relies on the bluntly fascist term “economic patriotism,” “patriotism” here meaning – as it always means in the mouths of tyrants — doing what the government demands.

Trump’s nationalism is of a funny sort, though: It is a nationalism of retreat rather than one of advance, the opposite of the expansive and expansionist approach of nationalist pin-up boy Vladimir Putin. It is a nationalism that contemplates a reduced and restricted American role in world affairs, rather than an enlarged and entrenched one, with the United States abandoning military commitment abroad and disengaging from international trade and cooperation.
