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.
When I came into office, the world was divided. Iran was resurgent. Iran is at its weakest point, economically, strategically, militarily, then since - then in many years. And we are going to continue to keep the pressure on to make sure that they do not get a nuclear weapon. That's in America's national interest and that will be the case so long as I'm president.
The biggest problems with Iran in the region are not due to the size of their resources, but due to the fact that they've been more effective in supporting proxies and stirring up dissension and conflict in the region than America or our allies have been in stopping those activities.
I have spent six years in prison, the last six years. Even if I was outside the prison, how much actual space was there for an investigative journalist to do his work in Iran? But I know one thing for sure: That we, the Iranian people, are much more in line of danger than the West.
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.
As long as Iran's aggressive policies continue, it's going to be bad for the region. Iran has to decide whether it wants a revolution or a nation-state.
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?
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.
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.
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.
Of course we [with Angela Merkel] discussed our commitment to meeting shared security challenges from countering cyber threats to ensuring that Iran continues to live up to the terms of the Iran nuclear deal.
We [USA] don't have diplomatic leverage to eliminate every vestige of a peaceful nuclear program in Iran. What we do have the leverage to do is to make sure that they don't have a weapon.
We've achieved this historic progress through diplomacy, without resorting to another war in the Middle East. I want to also point out that by working with Iran on this nuclear deal, we were better able to address other issues.
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.
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.
