Vice President JD Vance is set to lead renewed negotiations with Iran this weekend to bring an end to the U.S.–Israel war on the country that stretched into a second month. The talks come after a roller coaster of a week, which began with President Donald Trump threatening genocidal war crimes against Iran.

Trump urged Iran to make a deal with the U.S. and fully open the Strait of Hormuz by Tuesday at 8 p.m. ET. Then, shortly before the deadline, Trump took to social media again to say Iran and the U.S. had reached a two-week ceasefire agreement brokered by Pakistan. Trump said the U.S. received a workable 10-point plan from Iran to begin negotiations on a durable ending to the war. In the meantime, Iran said it would allow for safe passage through the Strait of Hormuz. Israel, however, immediately intensified its attacks on Lebanon, jeopardizing the already tenuous ceasefire. More than 300 people were killed in Lebanon by Israeli airstrikes the day after the ceasefire was announced.

The terms of the plan are not yet clear but there are some key factors for Iran, says Narges Bajoghli, a professor of Middle East Studies at Johns Hopkins University.

“One is that Iran is asking for non-aggression from the United States into the future. It won’t take the United States’s word for it. It’s already been burned by the U.S. multiple times,” Bajoghil tells The Intercept Briefing. “Then the other big thing is sanctions relief.” But “Iran’s biggest red line is its sovereignty and independence.”
