Rick Santorum in CNN/Salem GOP Debate

On Families & Children: FactCheck: Yes, ISIS declared fatwa to kill disabled kids

Could that be literally true? We checked; indeed it is: "ISIS has issued an order to exterminate children with Down syndrome, the Mosul Eye reported. The Sharia Board issued a fatwa to 'kill newborn babies with Down syndrome and congenital deformities and disabled children.' The group confirmed more than 38 cases where the terrorist organization executed babies born with disabilities using either lethal injection or suffocation. The victims were ages 1 week to 3 months, and killed in Syria and Mosul. ISIS claimed that children born with Down syndrome came from "foreign fighters" who married Iraqi & Syrian women. The order was issued by the terror group's Saudi judge Abu Said Aljazrawi." (NY Daily News, 12/14, reporting from "The Mosul Eye").

On Foreign Policy: Enemy is a theocracy; so understand their ideology

On Homeland Security: Political correctness hinders us from fighting terrorism

HUCKABEE: No. I'm not taking it away, I just want to make sure that everything we use is going to be effective. Let's use every tool, but let's also check out the Facebook posts, let's look at Twitter accounts. My gosh, we were told we couldn't do it because it might invade somebody's privacy.

SANTORUM: I agree with Gov. Huckabee, that we should in fact be looking at people's social media posts. That's just common sense. But we've defunded and tied the hands behind the backs of our intelligence agencies because of political correctness. We're not allowed to ask any questions or really pursue, whether there's any mosque that they're attending that could be spreading Jihadism. But we're not allowed to ask those questions, we're not allowed to pursue to those things because we have a president who denies the reality of the enemy we confront.

On Homeland Security: Iranian nuclear deal was worst treaty in US history

Gov. George PATAKI: Iran is our enemy. They are the number one sponsor of state terror. The Iranian Deal is a disaster. And by the way, I don't think the next president has to abrogate it. It was never ratified by the Iranians. They have tested long-range ballistic missiles in violation of U.N. resolutions. They have broken the agreement. It is void. They can never have a nuclear weapon and should not get relief.

On Homeland Security: Reverse policy on women in military combat roles

SANTORUM: I would use the studies that were done that were ignored by this military that there were certain positions that frankly were not suitable. And they pushed a political agenda above what is in the best interest of the safety, security, and effectiveness of our fighting units.

Q: So, you're saying, yes, you would change the policy back?

SANTORUM: I would change the policy to reflect what is the best interest of the people that we're asking.

Gov. George PATAKI: I completely disagree with Rick. I don't care if you're a man or a woman. I care if you're good and capable of doing the job.

SANTORUM: You agree with me. Because that's exactly what I said.

PATAKI: It's not. You said you would reverse the policy.

SANTORUM: If they can in fact do the job that any other person can do, I will allow them to do so. But if they cannot, I would reverse the policy.

On Homeland Security: Make terror watchlist transparent so we know how to get off

On Immigration: Our policy is magnet that says "amnesty"; that has to change

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. The reality is that we've seen since the events of 9/11, the president talks about how he's worried about discrimination and acts against Muslims. There's four times as many acts of violence against Jews than there are against Muslims. I never hear the president talk about that.

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: Bulk metadata collection doesn't violate privacy

On War & Peace: We must take land from ISIS Caliphate, under their own law

SANTORUM: ISIS is a caliphate, the first Sunni caliphate since 1924, when Ataturk disbanded the Ottoman Empire. Under Islamic law, good Muslims who see them as a legitimate caliphate are required to follow them. How do we defeat their caliphate? Well, it's very clear in Islamic law how you do so. You take their land. You have to take land back from the caliphate and in the Islamic world that delegitimizes the caliphate. It makes the caliphate unsuccessful. Therefore not blessed by Allah. Therefore, you should not follow it. We need to take back the land in Iraq and we need to use Sunni, not Shiites, not Iranian troops, not Shiite Iraqis, but Sunni Muslims in Iraq and the Kurds, the Peshmerga, and take back Iraqi land. I believe if we did that, you would see ISIS begin to collapse.

GRAHAM: You're not going to win that way, Rick. There's nobody left in Syria to train.

On War & Peace: World War III has begun; let's identify it
