Iran doubles down on homeland security and the lifting of all economic sanctions in any talks with the US. In an exclusive conversation with CGTN host Tian Wei, Foad Izadi, an associate professor in the University of Tehran's Faculty of World Studies, says Tehran will no longer tolerate persistent threats. He said US policies are undermining other nations' sovereignty. His message is clear: If past agreements can be abandoned, Iran will seek its own guarantees, potentially by leveraging transit routes through the Strait of Hormuz.
