US President Donald Trump has been having a very dark week indeed. After a white supremacist Nazi killed a woman during protests in Charlottesville over whether or not a Confederate statue should be allowed to stay up, Trump referred to the white supremacist groups fighting to keep the statue of the pro-slavery guy up as “us.” Not “them.” “Us.” And now, in response to the deadly ISIS terrorist attacks in Barcelona that left 13 people dead and over 100 injured, he’s calling back to a weird, debunked myth about the execution of Islamic soldiers by a US General.

POTUS called on Barcelona to remain ‘tough and strong’ in the face of adversity

Trump began his response to the terrorist attacks in Barcelona with a typical, by-the-numbers call for the people there to remain “tough and strong” in the face of Islamic State terror. But then it got weird. He said, “Study what General Pershing of the United States did to terrorists when caught. There was no more Radical Islamic Terror for 35 years!”

What Trump is referring to is an old myth (which has been officially debunked, by the way, but that’s just fake news, right?) that General Pershing dipped his bullets in pig’s blood before executing Islamic soldiers. Great idea, Donald.
