Anti-MAGA rocker Jack White dubbed President Donald Trump the “worst American of all time” after Trump said he’d be fine with Iran attacking Los Angeles or San Diego.

Addressing Republicans and conservatives from Southern California in a scathing Instagram post on Tuesday, The White Stripes rocker asked, “How do you feel about your Fuhrer recommending that the cities you live in get attacked?”

Telling readers to watch clips of Trump’s comments with their own eyes, he said, “Listen to the cult members CLAPPING and cheering for this. Let me take a wild guess: it was a joke, owning the libs, insert cult rhetoric here, etc.”

Slamming the president’s loyal legion of supporters, he went on, “The allegiance these people have to this corrupt felon is so laughable and ignorant. That’s right, a U.S. ‘President’ that recommended that two major cities in our country be bombed because they don’t give total allegiance to his ego.”

“Imagine any other President or elected official in history saying this. False flag incoming anyone?” the “Seven Nation Army” singer then asked, suggesting Trump might be priming people to blame any future attacks on outside forces.

“Just wait till next month when he begins enacting illegal measures to not allow democracy at the polls to prevail when the right lose badly in the mid term elections,” he warned.

“I’ve said it before and I’ll say it again: The Worst American of All Time,” White wrote, finishing his post with a hashtag of the acronym, “#TWAAT.”

During a rally in Nebraska on Monday, Trump told crowds the rise of fuel prices and other goods were just a “small price to pay for keeping the world safe.”

“They can take out a city, let ’em take out Los Angeles, let ’em take out San Diego,” he then added. “This is a very small price to pay.”

“The role of a president is to protect the country, not to actively threaten it and encourage attacks on American lives,” she wrote on X.
