Iran has signaled openness to a nuclear deal—if a proposed regional uranium consortium is based within its borders. The U.S. proposal, led by envoy Steve Witkoff, suggests shared enrichment oversight with countries like Saudi Arabia and Turkey under IAEA monitoring. However, Iran's Supreme Leader dismissed any plan not based on Iranian soil, calling it a national threat. With enrichment caps and underground work restrictions on the table, talks aim to balance nuclear transparency with Tehran’s sovereignty concerns. A sixth round of negotiations may take place this weekend.
