Republicans have spent the past half-century portraying themselves as more patriotic, more committed to national security than Democrats. Richard Nixon’s victory in 1972, Ronald Reagan’s victory in 1980 and George W. Bush’s victory in 2004 (the only presidential election out of the past seven in which the Republican won the popular vote) all depended in part on posing as the candidate more prepared to confront menacing foreigners.

And Barack Obama faced constant, scurrilous accusations of being too deferential to foreign rulers. Remember the “apology tour,” or the assertions that he had bowed to overseas leaders?

But now we have a president who really is unpatriotic to the point of betraying American values and interests. We don’t know the full extent of Donald Trump’s malfeasance — we don’t know, for example, how much his policies have been shaped by the money foreign governments have been lavishing on his businesses. But even what we do know — his admitted solicitation of foreign help in digging up dirt on political rivals, his praise for brutal autocrats — would have had Republicans howling about treason if a Democrat had done it.

Yet almost all G.O.P. politicians seem perfectly fine with Trump’s behavior. Which means that it’s time to call Republican superpatriotism what it was long before Trump appeared on the scene: a fraud.
