Shortly after Donald Trump’s Election Day victory, many jihadists voiced their pleasure with the result: “Rejoice with support from Allah, and find glad tidings in the imminent demise of America at the hands of Trump,” said one. Trump “reveals the true mentality of the Americans, and their racism toward Muslims and Arabs and everything. He reveals what his predecessors used to conceal. So his victory further exposes America and its appendages,” said another.

Trump — who pledged in his inaugural address to “unite the civilized world against radical Islamic terrorism” and “eradicate [it] completely from the face of the earth,” as well as previously promising to “bomb the shit out of” ISIS and “take out” the families of terrorists — likely sees himself as a staunch opponent of what he and the Right refer to as “Radical Islam.”

But there’s at least one problem with his self-perception: Trump’s proposed policies would only strengthen, not hinder, ISIS and other extremist groups. Indeed, after Trump issued his executive order barring entry to the United States citizens of seven predominantly Muslim countries, jihadist groups “celebrated . . . saying the new policy validates their claim that the United States is at war with Islam,” as Joby Warrick reported in the Washington Post.
