Everything we've done has been designed to make sure that we address that number one priority. That's what the sanctions regime was all about. That's how we were able to mobilize the international community, including some folks that we are not particularly close to, to abide by these sanctions. That's how these crippling sanctions came about, was because we [USA] were able to gain global consensus that Iran having a nuclear weapon would be a problem for everybody.
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.
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 United States is imposing sanctions on individuals and companies working to advance Iran's ballistic missile program, and we are going to remain vigilant about it. We're not going to waver in the defense of our security or that of our allies and partners.
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.
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.
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.
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.
Americans coming home, an Iran that has rolled back its nuclear program and accepted unprecedented monitoring of the program -these things are a reminder of what we can achieve when we lead with strength and with wisdom, with courage and resolve and patience. America can do and has done big things when we work together.
