The security of Tallinn was equal to us, as important as is Paris or Berlin or London.

We may need to hold the line against Putin in eastern Europe for some time to come.

Either Mr. Trump which is possible doesn't understand -- I mean that sincerely, he's a bright guy, I'm not saying that, not pretending. But he either doesn't understand because this is a realm in which he has never dealt before or he…

He will say, Joe, and folks, I have not been out responding to in my capacity as vice president to anything that Mr. Trump has said, but it is my view that a presidential candidate that publicly attacks a sitting federal judge who ruled in…

How can that be interpreted in any other way that as a direct threat? These are words of someone who sees our federal judiciary not as an independent branch of government, but as a tool for him to manipulate so he can do what he calls deal…

U.S. sanctions have been a very powerful and visible bipartisan signal of U.S. policy of standing firm on democracy.

Next door, in Burundi, President Nkurunziza's unconstitutional election to a third term last year sparked violence.

the Constitution of the United States, like many constitutions in Africa and around the world, limits him to two terms.

I believe that we need to work towards a more peaceful and stable future for the people of the world, and that means working to prevent nuclear proliferation and reducing the risk of nuclear war.

There needs to be a broad look at the functions and capabilities of NATO, taking into account what Russia has been up to.

I could not agree more, I do not think we should have done what we did in Libya.

the United States continues to lead aggressively around the world

International leadership does not involve a choice between sending in the 101st Airborne or doing nothing.
