CBS GOP S.C. Debate: on Foreign Policy

Donald Trump: Figure out who our allies are

TRUMP: What we want to do, when we want to do it, and how hard do we want to hit? We are going to have to hit hard to knock out ISIS. We're going to have to learn who our allies are. We have allies, we have no idea who they are in Syria. Do we want to stay that route, or do we want to go and make something with Russia?

Donald Trump: Iran deal is one of the worst I've ever seen

TRUMP: The Iran deal is one of the worst deals I have ever seen negotiated in my entire life. It's a disgrace that this country negotiated that deal.

Jeb Bush: Russia's Putin is not an ally of the US & everyone knows it

KASICH: First of all -- yes. We have to make it clear to Russia what we expect. We don't have to declare an enemy or threaten, but we need to make clear what we expect. Number one is we will arm the folks in Ukraine who are fighting for their freedom. Secondly, an attack on NATO is an attack on us.

TRUMP: We're going to have to learn who our allies are [against ISIS]. We have allies, we have no idea who they are in Syria. Do we want to stay that route, or do we want to go and make something with Russia?

BUSH: The very basic fact is that Vladimir Putin is not going to be an ally of the United States. The whole world knows this. It's a simple basic fact.

John Kasich: US should not be world's police in places like Iraq

Sen. Marco RUBIO: Saddam Hussein was in violation of U.N. resolutions, in open violation, and the world wouldn't do anything about it, and George W. Bush enforced what the international community refused to do.

KASICH: I don't believe the United States should involve itself in civil wars. Civil wars are not in our direct are interest. The fact is, is that we should go to war when it is our direct interest. We should not be policemen of the world, but when we go, we mean business. We'll do our job. We'll tell our soldiers, our people in the service, take care of your job and then come home once we've accomplished our goals.

Marco Rubio: Three main threats: Asia-Pacific, Middle East, and Russia

TRUMP: What we want to do, when we want to do it, and how hard do we want to hit? We are going to have to hit hard to knock out ISIS. We're going to have to learn who our allies are. We have allies, we have no idea who they are in Syria. Do we want to stay that route, or do we want to go and make something with Russia? But very important, who are we fighting with? Who are we fighting for? What are we doing?

RUBIO: There are three major threats. No. 1 is, what are we doing in the Asia-Pacific region, where North Korea and China pose threats to national security. No. 2 is, what are we doing in the Middle East with the combination of the Sunni-Shia conflict driven by the Shia arc that Iran is now trying to establish in the Middle East, also the growing threat of ISIS. The third is rebuilding NATO, particularly in Central and Eastern Europe, where Vladimir Putin is threatening the territory of multiple countries.

Marco Rubio: I voted against the president's inadequate Syria strategy
