There is going to be a nuclear arms race in the Middle East if Iran gets a nuclear weapon. And you are going to see it in Egypt, in Turkey, in the Emirates. All of those people will want that.
If Iran becomes a nuclear weapon state it is the end of non-proliferation as we know it. If Iran gets a nuclear weapon you are likely to see Saudi, Egypt and other countries follow suit and we will bequeath to the next generation a nuclear arms race in the world's most unstable region.
The alternative, no limits on Iran's nuclear program, no inspections, an Iran that's closer to a nuclear weapon, the risk of regional nuclear arms race, and the greater risk of war - all that would endanger our [American] security.
My red line is Iran may not have a nuclear weapon. It is inappropriate for them to have the capacity to terrorize the world. Iran with a nuclear weapon or with fissile material that can be given to Hezbollah or Hamas or others has the potential of not just destabilizing the Middle East.
Can you imagine what will happen to the global economy if Iran comes out with a nuclear weapon? The whole area will enter a nuclear race - Saudi Arabia, Turkey.
We will stop Iran from becoming a nuclear power. We will stop that nuclear arms race that could happen in the Middle East. We will also make that Putin knows we have brigades in eastern Europe to make sure we deter his aggression. Peace through strength works.
I think it's yet to be seen how that is going to shape up. But I can tell we all know that President-elect [Donald] Trump doesn't like the Iran deal, thinks it's a terrible document, thinks it will create a nuclear arms race in the Middle East, which it already is beginning to do.
The two biggest threats to international security in 2013 are Iran getting a nuclear weapon, and Iran being bombed to stop it getting a nuclear weapon. Both would precipitate a long and dangerous conflict in an already unstable Middle East. Both would be a disaster.
I think that Iran with a nuclear weapon is extremely destabilizing. I think it could precipitate a nuclear arms race in the region.
I don't want to use the term "nuclear weapons" because those people in Iran who have authority say they are not building nuclear weapons. I make an appeal to the countries who do have nuclear weapons. They don't consider them a nuclear threat. But let's say a country that doesn't have nuclear weapons gets involved in building them, then they are told by those that already have nuclear weapons that they oppose [such a development]. Where is the justice in that?
It's a deal that will lead to a nuclear Iran, an Israel that will be less safe and secure, and a much more dangerous Middle East. Let's ask it: Hillary Clinton, as an inept negotiator of the worst nuclear arms deal in American history. Is she guilty or not guilty?
A diplomatic solution that puts significant and verifiable constraints on Iran's nuclear program represents the best and most sustainable chance to ensure that America, Israel, the entire Middle East will never be menaced by a nuclear-armed Iran.
Without a deal [with Iran], the international sanctions regime will unravel with little ability to reimpose them. With this deal, we have the possibility of peacefully resolving a major threat to regional and international security. Without a deal, we risk even more war in the Middle East and other countries in the region would feel compelled to pursue their own nuclear programs, threatening a nuclear arms race in the most volatile region in the world.
On the nuclear issue, the first point is that the entire world must recognize that Iran does not seek a nuclear weapon, nor shall it seek a nuclear weapon.
Iran with a nuclear weapon or with fissile material that can be given to Hezbollah or Hamas or others has the potential of not just destabilizing the Middle East. But it could be brought here.
I want to reassert again the position of the United States that with regards to Iran, we will not allow Iran to develop a nuclear weapon, period. We will not allow them to develop a nuclear weapon, and we will exert all options in the effort to ensure that that does not happen...The United States stands firmly with Israel, and we have a rock solid commitment to the security of Israel and to the security of its citizens.
If Iran obtains nuclear weapons, then almost certainly Saudi Arabia will do the same, as will Egypt, Turkey and perhaps others in the region.
