'Literally insane' Trump outburst leaves CNN's Christiane Amanpour in disbelief

CNN's Christiane Amanpour could not believe that former President Donald Trump over the weekend floated not defending American allies were they to be attacked by Russia.

Appearing on the network on Monday, Amanpour was asked by host Poppy Harlow about any reaction she's heard from global leaders about Trump's remarks, which sparked a public rebuke from NATO Secretary-General Jens Stoltenberg.

"You know, Poppy, it is insane," she said. "It literally is insane. In one sentence, President Trump turned the entire post-war transatlantic security doctrine on its head."

Amanpour went on toe suggest that Trump's statements about NATO were a "propaganda coup" for Russian President Vladimir Putin, and expressed particular shock at Trump's claim that he would encourage Russian to attack NATO countries who were not paying what he deemed to be sufficient money for national defense.

"It's almost unbelievable, it's an insanity to say that," she said. "That's the existential crisis the world faces right now. The post-World War II global security operation is based on America and its 30 other NATO allies defending each other and coming to each other's rescue and protecting and securing democracy and security in the west."
