After a roundtable appearance on "This Week," former Secretary of State Madeleine Albright joined Martha Raddatz for an ABC News web exclusive. Albright discussed her career, gave advice for the current Secretary of State John Kerry, and talked about how U.S. foreign policy has changed since she served in the Clinton administration.

"I think that in many ways it's gotten much harder because we have this evolution of what we call 'non-state actors.' Various, obviously, terrorist groups that roam around. It's very hard to figure out what tools to use against them. And lack of faith, frankly, in the various international institutions that exist. It's uncharted waters in many ways."

Are you and Mrs. Clinton friends? Did you offer her any input during her time as our secretary of state?

"Yes, we're very good friends. And I always say I never would have been secretary of state without her. And the reason I know that is that President Clinton said so. And she and I did talk to each both when I was secretary and when she was secretary…Absolutely…when she was first lady and I was secretary we did a lot of tag team stuff together. Traveling abroad. She was one of America's great ambassadors. All her skills were put to work. I thought she was a fantastic secretary of state."

Think Hillary Clinton will run for president?

"I have no idea."

Is there anything she would like to go back and change?

"I would like to change something that happened when I was ambassador at the UN was our lack of help in Rwanda. I think we all think about that. I also do wish that we had been able to have Middle East peace that President Clinton worked so hard on."

What one key piece of advice would you like to give Secretary Kerry?

"Well, to understand what it is to represent the United States-that it's the greatest honor to be able to sit behind a sign that says "United States" and be able to use the goodness of American power to make a difference."

During your time as secretary of state, how did you take care of yourself and avoid stress related illnesses?

"Well, I loved what I did. I…did sleep when I could on command. I didn't exercise enough. Being secretary of state was a very fattening job because I was eating for my country. But I really enjoyed what I did. And I think that makes a big difference."
