Donald Trump doesn't embody Western values in the way that previous presidents such as John F. Kennedy and Barack Obama did, according to Wolfgang Ischinger, a former German ambassador to the U.S. who now heads the Munich Security Conference.

"We are losing that symbol of the West that used to be undisputed, the president of the U.S.," Ischinger said in an interview on Bloomberg TV. "I can't explain to my children that they should think of President Trump as the person that represents the values of dignity, of human freedom that the West stands for. That's a serious problem."

Ischinger's comments come two days after the U.S. president gave his inaugural speech to the United Nations General Assembly in New York, during which he said that "Rocket Man," as he refers to North Korean President Kim Jong Un, was on a "suicide mission" and that the 2015 nuclear agreement with Iran was "the worst deal ever" and should be revisited.
