President-elect Donald Trump could accomplish "something remarkable" in U.S. foreign policy, former Secretary of State Henry Kissinger says.

"Donald Trump is a phenomenon that foreign countries haven't seen. So, it is a shocking experience to them that he came into office. At the same time, extraordinary opportunity," Kissinger said in an interview aired Sunday on CBS' "Face the Nation."


"And I believe he has the possibility of going down in history as a very considerable president."

The new Republican president's "unfamiliar questions" could fill a vacuum left by President Barack Obama, who "basically withdrew" America from international politics, said Kissinger, who served enormous roles under two Republican presidents, Richard Nixon and Gerald Ford.

"Because of the combination of the partial vacuum and the new questions, one could imagine that something remarkable and new emerges out of it," Kissinger said. "I'm not saying it will. I'm saying it's an extraordinary opportunity."
