Trump's 'fiasco' in Davos will become a 'bright red line in history': columnist

President Donald Trump's speech at the World Economic Forum in Davos, Switzerland, on Wednesday was such a "fiasco" that one columnist thinks Americans will look back on it as a "bright red line in history."

Trump spoke in Davos in meandering terms about how he was skeptical that NATO would come to the U.S.'s rescue if needed, even though the alliance did just that after 9/11. He also called into question Denmark's right to own Greenland and made several misleading or false statements about his domestic accomplishments.

David Rothkopf, a columnist for The Daily Beast, discussed Trump's appearance on the world's stage with Joana Coles on a new episode of "The Daily Beast Podcast" on Wednesday.

"This is really a historical watershed," Rothkopf said. "For a hundred years, the U.S. has made building transatlantic relationships the foundation of peace and prosperity for us and for many, many people in the world. And it's over."

"It was a mess," Rothkopf said. "Trump was embarrassing. Trump was offensive. Trump was a bore. Trump was an idiot. But this is also a bright red line in history, and the world is not the world that it was when you woke up this morning, and it only promises to get worse and worse."
