Four sources told CNN that the Trump administration offered Iran a $30 billion investment in its own new civilian nuclear program. According to the sources, Iranians were also offered sanctions relief and the release of billions of dollars in blocked funds in talks that continued behind the scenes even during Operation 'Lion's Roar'. Two sources told CNN that several proposals were put on the table along with a demand for zero uranium enrichment by Iran, which has so far refused to commit to this.
