Fox News Sunday interviews during 2015: on Foreign Policy

Jeb Bush: Obama/Clinton/Kerry foreign policy caused global instability

John Kasich: Keep Iran accountable, WITHIN the existing Nuclear Deal

KASICH: We don't know what's going to happen in 18 months. I've been on the Defense Committee for 18 years, and you got to be careful not to paint red lines that you can't keep. In addition to that, I think we ought to hold Iran totally accountable for what they do, if they break any part of this deal, if they fund the radicals like Hamas and Hezbollah. In that kind of case, we've got to slap the sanctions back on. We would then have the high moral ground to talk to our allies and get them to go along with us. But in addition to that, if we get to the point where we think that Iran may be developing a nuclear [bomb], well then I think military action would be warranted. But let's wait until we get there and let's stay calm because that's one of the most important things we need to do when it comes to foreign affairs.

John Kasich: Syrian refugee situation is fundamentally a European crisis

KASICH: I support that. I think it's important that we don't let anybody infiltrate who's part of a radical group. But America needs to be part of this solution. It's fundamentally a European problem, but I think there are some things we can do. Beyond taking [in] these people, I think we can provide some logistical support so people aren't losing their lives. And in addition, maybe some humanitarian aid.

Q: And in the long run?

KASICH: We need to look at this as an opportunity to try to draw closer to our European friends. Finally, I think it's important that Europe and Western civilizations begin to stand up for their fundamental values, their primarily Jewish and Christian values, so that when these folks come, we can have assimilation. So they don't change us, but maybe in some way we either change them or live peacefully with them and we have full integration.

Ben Carson: Obama has turned his back on Israel

CARSON: All you have to do is go to Israel and talk to average people. And I couldn't find a single person there who didn't feel that this administration had turned their backs on Israel. And I think the position of president of the United States should be one where you begin to draw people together behind a vision. Not one where you castigate those who believe differently from you.

Q: what specifically is anti-Semitic in what the President is saying?

CARSON: I think anything is anti-Semitic that is against the survival of a state that is surrounded by enemies and by people who want to destroy them. And to ignore that and act like everything is normal there and that these people are paranoid, I think that's anti-Semitic.

Rick Perry: Priorities: Tear up agreement with Iran; secure US border

PERRY: Tear up that agreement with Iran. That's the biggest challenge I think that we have in this country and securing that border with Mexico is incredibly important as well, and those two things can happen on the first day.

Bobby Jindal: Bad Iran nuclear deal is worse than no deal

JINDAL: I think a bad deal is worse than no deal. I fear this administration could start a nuclear arms race in the Middle East. Sunni countries like Egypt, Saudi Arabia and Turkey are likely going to want their own nuclear capabilities This would be a threat to Israel, to Europe, to America. We're talking about an existential threat to the region, to the United States. Never mind the fact that we're not even asking Iran to recognize Israel, to cut off ties to terrorism, to release American prisoners. I'm just talking about giving up enriched uranium, giving up all their centrifuges, anytime, anywhere inspections. Those are the basic tenets of a basic deal. And it doesn't look like we're getting any of those things.

James Webb: Prefers confidence building gestures to deal with Iran

WEBB: I would be hesitant with what I see right now, what we do not want to do at this point is to send a signal to the region that we are accepting the notion that eventually Iran would be acquiring nuclear weapons. There are other ways we can improve relations with Iran, confidence building gestures as we did with the Soviet Union over many years.

James Webb: China is the greatest long term threat to America

WEBB: I would probably say China is a long-term strategic threat, if you look at the expansion that they have conducted over the last 15 years. I've been talking about in the South China Sea and building blue water navy. I take General Dunford's point about the turbulence with respect to Russia, but I think our friends and allies in Europe have done a pretty good job of helping us address that.

Q: As president, would you send weapons to the Ukrainians for example?

WEBB: I would be open to looking at that.

Marco Rubio: Opposes nuclear deal with Iran; but supported deal in 2012

A: Who would not be in favor of a deal if it would be a deal that Iran would allow themselves to walk away from any sort of enrichment or reprocessing? But that's not what the deal is. We now know what the outlines of the deal are and they're much worse than anybody anticipated. And in terms of saber rattling in our approach to terrorism: When you give these radical groups safe havens, whether it's in Syria or Iraq or Libya, they use those safe havens to carry out attacks against Americans and our allies, and increasingly here in the homeland.

Ben Carson: Military force is not off the table when it comes to Russia

CARSON: All options includes all options. That doesn't mean that would be my first option. When we look at Russia and we look at Putin, we can realize that he has great ambitions. His ambitions have been thwarted of late because of falling oil prices. And we should take note of that and realize that the economic weapon is a tremendous one in his case. We have incredible natural resources in this country in terms of oil, in terms of natural gas, but we have energy exportation rules from the '70s when we had an energy crisis that need to be gotten rid of, so we can use that to make Europe and other portions of the world more dependent on us. And that decreases his influence and his ability to expand.

Ben Carson: Would not go to war with Russia over Ukraine

CARSON: No, I wouldn't go to war over Ukraine, but I would handle Ukraine a very different way. You know, Ukraine was a nuclear arms state. They gave up their weapons. You know, it was agreed they would be protected if something happened with aggression. Have we lived up to that? Of course, we have not. And what does that say to our other allies around the world? It's not a good sign.

Lindsey Graham: Congress will not approve Iran nuclear deal

A: Don't think there's a snowball chance in hell that a Congress is going to approve this framework the way it's set up. The ayatollah saying he gets immediate sanction relief with no intrusive inspections.

Q: So what's your plan for a nuclear deal with Iran?

A: I will release today nine core principles of what I think a good deal will look like. Any time, anywhere inspections of military/nonmilitary facilities will be a bipartisan must. So, this idea that we can't go where we need to go is going to fail. The Chinese are talking about building five reactors for the Iranians. Any nuclear enrichment program must be limited to one reactor. At the end of the day, you can't lift sanctions until the behavior of Iran changes. They can longer be a state sponsor of terrorism before you lift sanctions down the road.
