At the center of his foreign policy vision, Donald Trump has put “America First,” a phrase with an anti-Semitic and isolationist history going back to the years before the U.S. entry into World War II. 

Trump started using the slogan in the later months of his campaign, and despite requests from the Anti-Defamation League that he drop it, he stuck with it.

Friday, he embraced the words as a unifying theme for his inaugural address.

“From this day forward, a new vision will govern our land,” Trump said on the Capitol steps. “From this day forward, it’s going to be only America First. America First.” 

Those same words galvanized a mass populist movement against U.S. entry into the war in Europe, even as the German army rolled through France and Belgium in the spring of 1940.
