Iran and the United States are poised Friday to hold negotiations in Oman at least over Tehran’s nuclear program. The talks follow a chaotic week that initially saw plans for regional countries to take part in talks in Turkey. Previous rounds of meetings turned to ash following Israel’s launch of a 12-day war against Iran back in June. The U.S. bombed Iranian nuclear sites during that war. Meanwhile, nationwide protests have shaken Iran's theocracy. It responded with a bloody crackdown that killed thousands and reportedly saw tens of thousands arrested. President Donald Trump has threatened to strike the country in the time since, spurring the talks.
