WASHINGTON - With President Bush trying to burnish his diplomatic credentials on a series of fronts, the State Department is pushing the envelope by suggesting it may be time to open a permanent American presence in – of all places – Tehran.
Secretary of State Condoleezza Rice has recently floated the idea of opening a US interests-section office in the capital of Iran – the last member of Mr. Bush's 2002 "axis of evil." An interests-section office, which is basically an embassy without an ambassador, allows for a US presence in a country with which the United States has no formal diplomatic relations.
The US maintains an interests section in Cuba – in a seafront high-rise in Havana. It is larger than the diplomatic missions of many countries with full diplomatic relations with the Cuban regime. - Christian Science Monitor
The U.S has had a storied history of dealings with Iran.
