I found Donald Trump to be very attuned to what was going on around the world.

The threat of nuclear warfare is very, very low. Trump is no fool, and he sees the world as a globalized world.

Donald Trump is a great listener, and he's a good challenger. He doesn't come across as a person who thinks he knows it all. In fact, he once told me he has had lot of things to learn.

Trump respects people who are selfish about their country. Putin is a guy who is very selfish about Russia and about the Russian federation, and he understands the history of his country. You can't say, "I don't like you." You've got to respect him. He's a world leader.

The Islamic ideology is a political ideology based on a religion.

Islam is an ideology and there's a religious component to it that's radicalized and in some cases it masks itself behind that religion, especially in America, because of freedom of religion.

Obama's decision to leave, to not sustain the victory that resulted after eight years of fighting, from 2003 to 2011 in Iraq, was another incredibly stupid decision. It was totally based on politics, not based on any notion of national security. It's a nightmare for our national security. And then you have the Libya intervention.
