Days after meeting with President-elect Donald Trump, elder statesman Henry Kissinger said one shouldn't expect Trump to give his voters exactly what he promised.

"One should not insist on nailing [Trump] into positions that he had taken in the campaign," said Kissinger during an appearance Sunday on CNN's "Fareed Zakaria GPS."


Kissinger argued that it is counterproductive to demand absolute consistency from presidential administrations, particularly in the face of fluid international situations.

Commending Trump on the effectiveness of his campaign tactics, the former secretary of state added: "The art now would be to develop a strategy that is sustainable, that meets the concerns that have appeared during the campaign but that can to be linked to some of the main themes of American foreign policy."

Kissinger, who met with Trump on Thursday, also told Zakaria that the Manhattan mogul's unique style of campaigning has put him in an unusual position.

"This president-elect is the most unique that I have experienced in one respect," he said: "No baggage."

Kissinger, 93, won a Nobel Peace Prize in 1973 for his efforts to end the Vietnam War, one of a number of polarizing events during his high-profile years as Richard Nixon's and Gerald Ford's leading foreign policy figure. Generations of American political figures have sought his counsel on international events and strategy.
