First GOP presidential debate: on Homeland Security

Mike Pence: Supports Reagan Doctrine: peace through strength

If we give in to Putin to give him his land [in Ukraine], it's not going to be too long for he rolls across a NATO border. And frankly, our men and women of our armed forces are going to have to go and fight him. I want to let the Ukrainians fight and drive and the Russians back out.

Vladimir Putin has been saying he wants to reestablish the old Soviet sphere of influence. He is a dictator and a murderer and the United States of America needs to stand against authoritarianism.

Give them a promise that Ukraine will never be an NATO. We achieve peace through strength. And America needs to stand for freedom.

Ron DeSantis: Keep military service voluntary instead of mandatory

DESANTIS: I think it should be voluntary. I'm somebody that volunteered to serve, inspired by September 11th. When you go in that type of environment, anything you have, your personal agenda, you check it at the door. You go there and it's about focusing on the mission above all else. That's how I would view being the president of the United States. It's not about me. My sole focus will be on your future and reversing this country's decline.
