President Joe Biden spent part of his overseas trip wringing his hands over the possibility that global temperatures could rise by 1.5°, calling the prospect “more frightening than nuclear war.”

Biden made the comments from a Hanoi, Vietnam, press conference – during which he also referred to those who didn’t buy into climate alarmism as “lying dog-faced pony soldiers” and claimed that he’d borrowed the line (which he’s used before) from an old John Wayne movie.

Biden first called on his Special Envoy for Climate John Kerry, who he said had forgotten more about emissions than most could ever learn.

“Correct me if I get this wrong, John, but I’m quite sure I’m right,” he said. “And that is that there’s more carbon absorbed from the air into the Amazon region, into the ground — the ground — than emitted in the entire United States on the same basis.”

“Now imagine if people go in and do what we did, 150-200 years ago — and cut down the forest and start farming in that area,” Biden continued, going on to say that the larger and wealthier nations should be doing what they could to prevent developing nations from employing those same strategies.

“In addition to helping the environment overall — and the only existential threat humanity faces, even more frightening than a  — than a nuclear war, is global warming going above 1.5° in the next 20, ten years,” Biden added. “It would be real trouble, There’s no way back from that.”

During the same press conference, Biden referred to “climate deniers” as “lying, dog-faced pony soldiers” — a line he’s used before and claims he picked up from a John Wayne film.

“My brother loves having these famous lines from movies, famous quotes,” Biden prefaced, adding, “And one of them is there’s a movie about John Wayne, he’s an Indian scout, and they’re trying — I think it was Apache or one of the great tribes of America back on a reservation.”

The president went on to say something about the headdresses and Union soldiers who were apparently trying to get the Native Americans to go with them somewhere, promising them they’d be taken care of.

“And the Indian scout points to the Union soldier and says, ‘He’s a lying, dog-faced pony soldier,'” Biden continued. “Well there’s a lot of lying, dog-faced pony soldiers out there about — about global warming.”

But despite Biden’s insistence that he stole the line from the Duke, TMZ reported that the quote — as Biden delivered it — does not actually exist. Instead, it appears to be a strange mash-up of John Wayne lines crossed with a 1952 Tyrone Power film titled “Pony Soldier.”

President Joe Biden said on Sunday he does not want to isolate China as he works to shore up ties between the United States and other countries.

The commander in chief made the assertion during a press conference in Hanoi, Vietnam, after participating in a G-20 summit in India that Chinese President Xi Jinping did not attend.

“So, really, what this trip was about — it was less about containing China. I don’t want to contain China,” Biden said. “I just want to make sure that we have a relationship with China that is on the up and up, squared away, everybody knows what it’s all about.”

Biden further explained that his itinerary was about “having India cooperate much more with the United States, be closer with the United States, Vietnam being closer with the United States.”

He also insisted that his travel abroad was meant to create “a stable base in the Indo-Pacific” and establish international “rules of the road” on matters related to the ocean, airspace, and space.

“I want to see China succeed economically, but I want to see them succeed by the rules,” Biden added.

Rep. Michael McCaul (R-TX), chairman of the House Foreign Affairs Committee, criticized Biden during an appearance on CNN’s “State of the Union.”

“The whole point of him going to the region, in my view, was to get our friends and allies and partners together in the event of an invasion of Taiwan and a greater invasion into the South Pacific Sea,” McCaul said, adding that Biden chose the “wrong message to send” because it was not one of “deterrence.”

Ahead of Biden’s visit to Vietnam, Beijing expressed disapproval of the U.S. approach to dealing with China’s neighbors.

“We believe that when dealing with relations with Asian countries, the #US should abandon the Cold War mentality of a zero-sum game, abide by basic norms of international relations, not target third parties and not undermine regional peace, stability, development and prosperity,” said Chinese Foreign Ministry spokesperson Mao Ning, as reported in a post to X by China’s Global Times.

During his press conference, Biden stressed, “I think we think too much in terms of Cold War terms.”

The president said he spoke with Xi’s No. 2 Chinese Premier Li Qiang at the G-20 summit about “stability”and their conversation “wasn’t confrontational at all.” Biden also said he hopes to meet with Xi “sooner than later.”
