Donald Trump: Now look, we are going to get rid of ISIS, big league. And we're going to get rid of 'em fast. And we're going to use surrounding states. We're going to use NATO, probably. And we're going to declare war. It is war. When the World Trade Center comes tumbling down, with thousands of people being killed, people are still-- I have friends that are still--

Lesley Stahl: But we did go to war, if you remember. We went to Iraq.

Donald Trump: Yeah, you went to Iraq, but that was handled so badly. And that was a war-- by the way, that was a war that we shouldn't have entered because Iraq did not knock down--excuse me

Lesley Stahl: Your running mate--

Donald Trump: Iraq did not--

Lesley Stahl: --voted for it.

Donald Trump: I don't care.

Lesley Stahl: What do you mean you don't care that he voted for?

Donald Trump: It's a long time ago. And he voted that way and they were also misled. A lot of information was given to people.

Lesley Stahl: But you've harped on this.

Donald Trump: But I was against the war in Iraq from the beginning. ( *Note from Raine: see below)

Lesley Stahl: Yeah, but you've used that vote of Hillary's that was the same as Governor Pence as the example of her bad judgment.

Donald Trump: Many people have, and frankly, I'm one of the few that was right on Iraq. (again - see note from me, below)

Lesley Stahl: Yeah, but what about he--

Donald Trump: He's entitled to make a mistake every once in a while.

Lesley Stahl: But she's not? OK, come on--

Donald Trump: But she's not--

Lesley Stahl: She's not?

Donald Trump: No. She's not.

Lesley Stahl: Got it.

Over the course of 20 minutes, the mood shifted from painfully tense to unbearably, painfully tense as Trump repeatedly interrupted both interviewer Lesley Stahl and new best friend Pence, who spent the majority of the time chuckling off to the side while everyone talked about him like he wasn’t right there.

At one point, Trump gave Pence permission to speak before talking right over him. At another, Trump interjected, “I’m much more humble than you would understand.”

Lesley Stahl: You're not known to be a humble man. But I wonder--

Donald Trump: I think I am, actually humble. I think I'm much more humble than you would understand.

Lesley Stahl: As you think about-- prospect of running this country in these tough times where the world is spinning apart-- are you awed? Are you intimidated? Are you humbled by the enormity of this?

Donald Trump: You just said it best.

Mike Pence: Mmm.

Donald Trump: In a world that's spinning apart. That's what I'm thinking of. I'm not thinking of, "Oh gee, isn't this wonderful? Isn't this great what I've done?" I've had people that said, "It doesn't matter if you win or lose, what you've done has never been done before. You're gonna go down in the history books." You know what I say to 'em?" I say, "You're wrong." I will consider it, 'cause I funded my own primaries, I'm funding now a lot of this campaign. I'm putting in, you know-- I've spent $55 million in the primaries. I'm spending a fortunate now. I'll tell you, it is spinning. Our world is spinning out of control. Our country's spinning out of control. That's what I think about. And I'll stop that.

Lesley Stahl: Not-- humbled or-- awe.

Mike Pence: I can say to 'ya-- what--

Lesley Stahl: Go ahead.

Mike Pence: Talking with him in private settings, I love the words you used because this man is awed with the American people, and he is not intimidated by the world. And Donald Trump, this good man, I believe, will be a great president of the United States.

Donald Trump: I love what he just said.
