Second, we’re strengthening the global regime — including the Nuclear Non-Proliferation Treaty — that prevents the spread of nuclear weapons. We’ve succeeded in uniting the international community against the spread of nuclear weapons, notably in Iran. A nuclear-armed Iran would have constituted an unacceptable threat to our national security and that of our allies and partners. It could have triggered a nuclear arms race in the Middle East and begun to unravel the global nonproliferation regime.

After Iran initially rejected a diplomatic solution, the United States mobilized the international community to impose sanctions on Iran, demonstrating that nations that fail to meet their nuclear obligations will face consequences. After intense negotiations, Iran agreed to a nuclear deal that closes every single one of its paths to a nuclear weapon, and Iran is now being subjected to the most comprehensive inspection regimen ever negotiated to monitor a nuclear program. In other words, under this deal, the world has prevented yet another nation from getting a nuclear bomb. And we’ll remain vigilant to ensure that Iran fulfills its commitments.

Third, we’re pursuing a new framework for civil nuclear cooperation so countries that meet their responsibilities can have access to peaceful nuclear energy. The international fuel bank that I called for seven years ago is now being built in Kazakhstan. With it, countries will be able to realize the energy they seek without enriching uranium, which could be at risk of diversion or theft.
