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.
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.
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.
We have two kinds of oppression. Oppression that is universal - everyone in Iran is subject to it. But everyone has also their own, unique way of experiencing this oppression.
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.
If Iran does not take steps in the near future to live up to its obligations, then the United States will not continue to negotiate indefinitely... Our patience is not unlimited.
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.
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.
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.
Like twentieth-century Iran, the remnant of the Persian Empire, Ethiopia under Haile Selassie attempted to preserve the absolutist state throught an accommodation with modernizing forces in his own terms without completely subduing traditionalists. This was not a strategy of Haile Selassie's own choosing. Instead, he was overtaken by events and forced to deal with contradictions that were from the very beginning too formidable to be managed in the long term.
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.
Iran has made vile comments, anti-Semitic comments, comments about the destruction of Israel. It is precisely for that reason that even before I became president, I said Iran could not have a nuclear weapon.
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.
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.
