Lindsey Graham in CNN/Salem GOP Debate

On Homeland Security: American Muslims are the solution, not the problem

On Immigration: Change comprehensive reform plan to account for terrorism

GRAHAM: Well, the first thing I would do is make adjustments to reality [of ISIS and terrorism]. I would make changes to that bill in light of what I know today.

SANTORUM: Lindsey says this is a real war, until it comes to immigration. And, then, all of a sudden it's not such a real war.

Q: What would you do?

SANTORUM: We've created a magnet. We're attracting people. We have a policy that says amnesty. The world hears this, and knows that if they can come across this border, by and large, they're going to be able to stay. That has to change.

On Technology: You're isolationist if you don't monitor calls from abroad

On War & Peace: If Syrian war goes on another year, Jordan's king might fall

Dr. Ben CARSON: I asked the Syrians themselves: What do you want? Their supreme desire was to be settled back in their own country. I said, "What can America do?" They said, "Support the efforts of those who are trying to provide safety for us, including the Jordanians." They had a brand new hospital, for instance, that was unstaffed because there wasn't enough money to do it. But if you go into Hasakah province, that's an area that's as big as Lebanon. It's controlled by the Kurds, the Christians and the moderate Sunnis. You could settle a lot of people there.

GRAHAM: I've been to the refugee camps in Turkey, and Jordan. We've got to stop this war. Do you realize that there are more Syrian refugees in Lebanon going to school than Lebanese children? Do you realize if this war goes for another year the King of Jordan could fall? Let's have a no-fly zone.

On War & Peace: There's nobody left in Syria to train; bring in other Arabs

GRAHAM: You're not going to win that way, Rick. There's nobody left in Syria to train. Between the Russians and Assad, they have killed all the people we trained. I would get the Arabs who are threatened by ISIL just as much as we are, along with Turkey. We would use their armies. They have modern armies. 90% them, 10% us, and we go in and destroy the caliphate.

On War & Peace: Form army--90% them, 10% us--to destroy Caliphate

GRAHAM: I would get the Arabs who are threatened by ISIL just as much as we are, along with Turkey. We would use their armies. They have modern armies. 90% them--but some of us have to go, folks. You're not going to keep the war from here if some of us don't go over there. 90% them, 10% us, and we go in and destroy the caliphate. There must be American boots on the ground in Syria to win. If you don't understand that, you're not ready to be Commander in Chief.

Q: You called for U.S. ground troops in both Iraq and Syria...

GRAHAM: Two years ago. If we had 10,000 troops left in Iraq, there would be no ISIL and I hate what Obama did. He gave away everything we fought for.

On War & Peace: 10,000 US troops in Iraq; 10,000 in Syria; plus 90,000 Arabs

GRAHAM: Yeah. I just don't make this up; I talk to people who are combat trained who have won in Iraq who I trust. Here's what I want to tell the Arab world and Turkey. We're not going to send 100,000 troops. You're going to do the fighting this time and we're gonna help you. We paid for the last two wars, you're gonna pay for this one. They get it because ISIL wants to cut their heads off, too. [The Turks and Arabs] have modern armies: 90% them, 10% us, and we go in and destroy the caliphate. The point I'm trying to make is, there needs to be a ground component. We need to be smart, and we need to fight the war over there. And to the people in my party who believe you can withdraw from the battlefield like Senator Cruz and Paul and we be safe, you really don't understand this war.

On War & Peace: Don't collaborate with Russia & Iran to keep Assad in power

Sen. CRUZ: We need to learn from history. Obama, Clinton, and far too many Republicans--want to topple Assad. Assad is a bad man. But if we topple Assad, the result will be that ISIS will take over Syria. And I'll tell you whose view on Assad is the same as mine. It's Israeli Prime Minister Netanyahu. Netanyahu doesn't want to see Syria governed by ISIS. And we need to focus on American interests, not on global aspirations...

On War & Peace: To destroy ISIL in Libya, take the Caliphate's headquarters

GRAHAM: I want to talk to General Keane first. I want to find out, what do we need militarily to keep them contained and eventually destroy them in Libya? They're in nine countries. You want to deal with Libya, go to Iraq and Syria. You want to prevent another 9/11, take the caliphate headquarters away from ISIL. There is no other way to do it without a ground force going into Syria.

On War & Peace: Declaring war on Islam only helps ISIL

GRAHAM: This is a religious war between radical Islam and the rest of the world. And there's only one way you're going to win. Help people in Islam who reject radical Islam to fight over there and destroy this ideology. Donald Trump has done the one single thing you cannot do. Declare war on Islam itself. ISIL would be dancing in the streets. Declaring war on the religion only helps ISIL.

On War & Peace: Winning in Iraq is more important than safety

On War & Peace: We are at war and it's a religious war
