The president [Barack Obama] is not willing to send in apaches and spotters if the Iraqis say they don't want them and if it means that these Shia mobilization forces are going to be going after and trying to kill Americans.

I would need to see changes in the Iraq governance. Otherwise I don't think strikes are going to have any impact and could be very well counterproductive.

America has a critical role to play as the most powerful member of the world community.

Whether we kept a certain number of troops there or pulled out completely, if we can't get the Maliki government to include a large segment of its population in its security forces and protection, then the small amount of forces that we would have left there might have slowed this day, but they wouldn't have prevented it altogether.

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.

In fact, the converse is true: At a time when the United States has been called on for a level of moral leadership, vision and inspiration not seen since World War II, we cannot afford to dissemble about crimes against humanity.

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.
