Former Def Sec Robert Gates: Trump’s Tough Talk Got North Korea’s Attention [VIDEO]

He puts the odds of immediate success 'very low'

Watch above.

Former Secretary of Defense Robert Gates said in an interview aired Sunday that President Trump's tweets and tough rhetoric caught the attention of North Korea.

"I think the president's tough talk and the willingness of the Chinese and the Russians to agree to the toughest sanctions we've ever really applied to North Korea certainly increased the pressure on the North Koreans to come to the table," Gates told CBS's Margaret Brennan on "Face the Nation" ahead of a planned summit between Trump and North Korean leader Kim Jong Un. "So, I think that's an important piece of it."

Gates also focused on the president's "unpredictability."

"I think that the unpredictability in terms of some of the tweets and some of the tough talk did get the attention of the North Koreans and the Chinese as well -- in terms of fire and fury and so on," he said.
