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.
