Trump just cited a debunked story about a general who shot Muslims with bullets dipped in pigs' blood to send a message to terrorists

President Donald Trump on Thursday revived a long-debunked story he once told on the campaign trail about a US general who dipped bullets in pigs’ blood during a brutal campaign against insurgents.

In a tweet after what authorities are treating as a terrorist attack in Barcelona, Spain, the president again advocated the US follow the example of Army Gen. John Joseph “Black Jack” Pershing, who was the governor of the Philippines during the US occupation of the islands during the early 20th century.

“Study what General Pershing of the United States did to terrorists when caught,” Trump wrote. “There was no more Radical Islamic Terror for 35 years!”

Trump has claimed previously that Pershing dipped bullets in pigs’ blood to deter Muslim insurgents from committing violence. (Some Muslims believe that pigs’ blood is unholy.)

“He had his men load his rifles, and he lined up the 50 people, and they shot 49 of those people,” Trump said at a rally in February 2016. “And the 50th person, he said, ‘You go back to your people, and you tell them what happened.’ And for 25 years, there wasn’t a problem.”

Fact-checkers have dubbed the Pershing story unproven at best.

Politifact wrote in 2016 that while there was some evidence that the United States used pigs as a tactic against Muslim insurgents, Trump’s claim was still unsupported.

“There is no evidence that Pershing himself committed these acts, there is nothing said about the use of 50 bullets dipped in pig’s blood, and most important, there is no evidence to support Trump’s claim that this tactic was effective in stopping violence — or that it would provide a useful policy today,” the site says.
