U.S. Secretary of State Mike Pompeo has unveiled a far-reaching list of demands for any new nuclear deal with Iran, and threatened economy-crushing sanctions if Tehran does not change its behavior.

The 12-point list of demands came in a Monday speech at the conservative Heritage Foundation that laid out the Trump administration's strategy after pulling out of the Iran nuclear agreement earlier this month.

Under any new deal, Pompeo insisted, Iran must indefinitely abandon nuclear weapons work and provide United Nations inspectors access to sites anywhere in the country.He said Tehran must also end its proliferation of ballistic missiles and stop its "destabilizing activities" across the Middle East.

If Iran does not change course, the U.S. "will apply unprecedented financial pressure," Pompeo warned.

"These will be the strongest sanctions in history by the time we are done," said Pompeo. "The [Iranian] regime has been fighting all over the Middle East for years. After our sanctions come into full force, it will be battling to keep its economy alive."

Iran's President Hassan Rouhani dismissed the threats.

"Who are you to decide for Iran and the world?" Rouhani said in a statement published by Iranian state media on Monday. "The world today does not accept that the United States decides for the world. Countries have their independence."
The Trump administration has vowed to reimpose sanctions that were lifted as part of the 2015 nuclear agreement, which was signed between Iran, the United States, and several European countries, as well as Russia and China. Washington has also imposed additional sanctions.

European countries are holding talks with Iran to try to salvage the deal. But it's not clear whether the effort can succeed. On Sunday, Iran's foreign minister, Javad Zarif, said the European Union's "political will is not enough to preserve the deal.”
EU foreign policy chief Federica Mogherini reacted to Pompeo's speech Monday by saying there is "no alternative" to the existing agreement, formally known as the Joint Comprehensive Plan of Action (JCPOA), and that European nations are already using sanctions to pressure Iran to change its behavior.
