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 ecological movement is concerned about this, and this is in here, where everything is public. In Iran, where everything is covert, we have no firsthand information.
When al-Qaeda was on the run from Afghanistan crossing through Iran, some were arrested and they are imprisoned. Some of them are charged with some actions in Iran.
What we've seen at least since 1979 is Iran making constant, calculated decisions that allow it to preserve the regime, to expand their influence where they can, to be opportunistic, to create what they view as hedges against potential Israeli attack in the form of Hezbollah and other proxies in the region.
If you're saying that Prime Minister [Benjamin] Netanyahu got fired up, he's been fired up repeatedly during the course of my presidency, around the Iran deal and around our consistent objection to settlements.
There's no way to resolve Syria without Iran being involved, given its financing of Assad and the fact that Hezbollah is probably the most effective fighting force that Assad can count on.
We did not treat the Americans badly. They left Iran in a relaxed mood. The embassy was active here after the revolution. We didn't have any problem with them. They started it.
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.
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.
That may prevent us from getting a deal done, It is there to be had. Whether ultimately Iran can seize that opportunity - we will have to wait and see, but it is not for lack of trying on our part.
The number of the opposition has certainly increased [in Iran]. There is more disgruntlement, but because there is no media, the voice of this opposition is not heard outside Iran.
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.
We have a historic opportunity to prevent the spread of nuclear weapons in Iran, and to do so peacefully, with the international community firmly behind us. We should seize that chance.
We can certainly be on the same side and the same front with the workers and with the oppressed people of Iran. We can certainly be on the same front with them.
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.
For decades, our differences with Iran meant that our governments almost never spoke to each other. Ultimately, that did not advance America's interests.
