Pink Floyd legend Roger Waters has gone nuclear on the current political climate, calling the presidential campaign a “bizarre charade, ” labeling Donald Trump as “ludicrous” and torching the UN as “toothless.”

“The most bizarre charade anywhere on earth, I would say, is this weird thing that goes on when you guys have a presidential election campaign. It goes on for a few years and is complete nonsense from beginning to end,” the British rocker said at a luncheon Monday for his new concert doc, “The Wall,” which doubles as an anti-war statement.

Waters also touched on Trump’s plan to build a wall between the US and Mexico and Scott Walker’s wall on the Canadian border. “They are equally ludicrous,” he told the crowd at Le Bernardin. And of the United Nations, he added, “We’re still floundering around allowing one or two very powerful nations to dictate policy … Unfortunately the United Nations is toothless.”

Waters said of Pope Francis, “[He] seems a perfectly decent chap,” but took aim at the Church. “It’s inevitable that they will eventually be dragged kicking and screaming into the 21st century and it remains to be seen whether or not they will actually develop a more reasonable attitude to women and pregnancy and birth control and pedophilia and all the other things they’ve been so laggedly about addressing for the last 2,000 years.”

Waters, who is going through a divorce with Laurie Durning, says when he wrote his album “The Wall,” “I’d only been through two or three divorces at the time.” But as he’s aged, he’s become more cynical, saying, “Our glorious leaders screw up the way this small, weak, cooling planet is organized, in ways that cause enormous distress to many if not most of our brothers and sisters all over the globe.”

Even the he music industry didn’t escape his wrath: “It actually now belongs to Colonel Sanders or Volkswagen. It no longer actually belongs to the people who wrote it or made it … It’s much more likely that we will end up in a world populated entirely by Simon Cowell and his awful boy bands.”
