Senate Minority Leader Mitch McConnell (R-KY) has been awfully chummy with President Joe Biden as of late after he teamed up with him on his infrastructure deal. The Republican threw all of that out the window on Tuesday, however, when he publicly turned on Biden over the ongoing crisis in Afghanistan.

While appearing on Fox News, McConnell described the Taliban takeover of Afghanistan in the wake of the withdrawal of U.S. troops as a “foreign policy blunder of gargantuan proportions that’s a stain on our national reputation and will be remembered for decades.”

“This is one of the greatest foreign policy disasters in American history,” McConnell said. “[T]he decision to pull out was a gargantuan mistake, in my opinion. Having made that decision, you would have to conclude these guys couldn’t organize a two-car funeral. I mean, here’s where we are — the president needs to forget about the August 31 deadline. We need to send in enough … military personnel to rescue our people.”

Not stopping there, McConnell went on to add that the fall of Afghanistan is “dramatically worse than Saigon in 1975.” He also claimed that the difference is “there weren’t terrorists in Vietnam threatening to attack” on U.S. soil.

“I think it’s a lot worse than Saigon in 1975,” McConnell explained. “There weren’t terrorists in Vietnam threatening to attack us here on U.S. soil. This is dramatically worse than Saigon in 1975 because Al Qaeda on the way back in, the same group with allied terrorist organizations that want to hit us here at home, will be able to operate freely throughout Afghanistan. So, this is considerably worse than the fall of Saigon.”

This comes after Barack Obama’s former Joint Chiefs of Staff Chairman Ret. Admiral Michael Mullen said that the United States should have learned from the withdrawal of troops form Saigon during the Vietnam War.

“I think we need to examine in the military that that can-do spirit and — and that can we understand why we too often say yes to a mission when we should say no,” Mullen said. “Nobody wants the Saigon image and, obviously, we ended up with another Saigon image that will last permanently, quite frankly, whether we like it or not.”
