On the way back from Mumbai to go meet with President Xi in China, I stopped in Singapore to meet with a guy named Lee Kuan Yew, who most foreign policy experts around the world say is the wisest man in the Orient.

I consider myself to be as informed on American foreign policy as anyone in America.

Foreign policy is like human relations, only people know less about each other.

American foreign policy, for all its shortcomings, has underpinned political stability around the world.

Foreign policy is an explicitly amoral enterprise.

Presumptuous for me to say, but at least - at a minimum - I've been able to influence the direction of the Democratic Party on foreign policy. And I've been relatively - presumptuous to say - relatively successful legislatively in the Senate, being able to win a lot of Republican friends, and being able to cross the aisle.
