I think Hillary Clinton is right. I think it isn't enough to leave [Bashir] Assad in place, because as long as he is there, there is going to be a recruiting magnet for ISIS.

It is now conventional wisdom that Americans do not care why we went to war in Iraq, that it is enough that the world is better off without Saddam Hussein.

Euphemisms, vague terminology or calls for discussions with Turkey to get at the truth are just some of the dodges Congress and the administration have used to avoid Turkish discomfort with its Ottoman past.

I think what we are confronting now is a new war of ideas. It's not communism versus capitalism, but it is authoritarianism versus democracy and representative government. And that is a threat that here in Europe, they feel acutely. They've seen their countries interfered with, bombarded by cyber-attacks, by Russian propaganda, indeed, by Russian troops.

A tremendous number of people come to the country legally, but overstay their visas. And there has to be a far stronger mechanism for being able to track down people, have overstayed their visas, to have a responsibility for who they're coming to visit or stay with.

I think Barack Obama has the overall right strategy and he's been right to resist bringing in massive numbers of American troops. The Iraqis would love to have Americans die for Iraq and the Syrians would love to have Americans die for Syria.

There are many reasons why the Russians prefer Donald Trump.I think, in the first instance, they wanted to tear down Secretary Clinton. They, I think, despised her remarks about the flawed 2011 elections in Russia. They feared that she would be very tough on Russia in terms of sanctions.
