Iran withholds reply to Vance’s letter; shift in U.S. tone seen as ‘positive signal’

Iran has not yet responded to a letter from US Vice President JD Vance that proposed resuming negotiations with Supreme National Security Council Secretary Mohsen Rezaei, who said on October 31 in a state broadcast interview that Washington's tone had "completely changed" and called it "a good signal," according to Press TV. Rezaei declined to disclose the letter's contents, saying the US had not made it public, and noted that diplomatic contacts through intermediaries have continued for over a month. He reiterated that Iran will not negotiate with the US until its conditions are met, while internal discussions continue over whether existing nuclear policy principles would be maintained if war resumes. The development signals a potential thaw in US-Iran tensions, which carry implications for oil prices, sanctions policy, and regional risk sentiment. Watch for whether Iran formally replies to the letter, any movement on its preconditions for talks, and signs of an official shift in nuclear policy.
