The US and Iran have not had relations since 1979. There have been no serious overtures to start up relations given the United States' opposition to Iranian nuclear ambitions and Iran's position on Israel. The biggest progress is the recent agreement between the US, Europe, and Iran on the rules by which the nuclear negotiations would go.
