The bottom line is this - whereas Iran was steadily expanding its nuclear program, we have now cut off every single path that Iran could have used to build a bomb.
Whatever Iranian people have bought, they have bought in the black market. It is not clear what they have bought, how many secondhand materials they have bought. I am very worried that something like Chernobyl will happen to Iran.
The North Korean regime remains one of the world's leading proliferator of missile technology, including transfers to Iran and Syria. The transfer of nuclear weapons or material by North Korea to states or non-state entities would be considered a grave threat to the United States, and we would hold North Korea fully accountable of the consequences of such action.
What the United States has to do is send a clear message to Iran that they will not be able to develop nuclear weapons. Why endure the difficulty of sanctions if they are not going to be able to develop nuclear weapons anyway?
International inspectors are on the ground and Iran is being subjected to the most comprehensive, intrusive inspection regime ever negotiated to monitor a nuclear program. Inspectors will monitor Iran's key nuclear facilities 24 hours a day, 365 days a year. For decades to come, inspectors will have access to Iran's entire nuclear supply chain. In other words, if Iran tries to cheat - if they try to find build a bomb covertly, we will catch them.
The Gulf States are extraordinarily suspicious of Iran for good reason. They view Iran as meddling in their affairs. They have seen Iran level asymmetric attacks against their facilities or their interests.
Iran's Supreme Court has issued a fatwa against the development of nuclear weapons. President [Hassan] Rouhani has indicated Iran will never develop nuclear weapons. I've made clear that we respect the right of the Iranian people to access peaceful nuclear energy in the context of Iran meeting its obligations.
As you know, we don't have relationships with Iran. I mean, that's - ever since the late '70s, we have no contacts with them, and we've totally sanctioned them. In other words, there's no sanctions - you can't - we're out of sanctions.
The other thing is going to be me being able to show not just the American people or the Israeli people but the world that, in fact, we have mechanisms in place that will prevent Iran from having a nuclear weapon.
I did not suggest that Iran is a democracy; just the opposite. I talked about it being a repressive theocracy. What I think is indisputable is that even within this repressive regime, the political leaders there - including the Supreme Leader - are sensitive to the concerns of the population within bounds.
Over more than a decade, Iran had moved ahead with its nuclear program. And before the deal, it had installed nearly 20,000 centrifuges that could enrich uranium for a nuclear bomb.
When it comes to preventing Iran from obtaining a nuclear weapon, I will take no options off the table. ... That includes all elements of American power: a political effort aimed at isolating Iran, a diplomatic effort to sustain our coalition and ensure that the Iranian program is monitored, an economic effort that imposes crippling sanctions and, yes, a military effort to be prepared for any contingency.
