The US also hopes to establish a diplomatic presence in Tehran for the first time in 30 years, according to the Guardian newspaper.
In a surprising development in the tense American-Iranian relationship, the US announced this week that it would send a high-level State Department official to attend talks with Iranian nuclear negotiators in Switzerland over the weekend. This unexpected policy turn comes after a tense, saber rattling summer during which the US, Israel, and Iran have traded threats, staged war games, and tested weapons. But observers suggest that the shift in the US's longstanding tactic of isolating Tehran may be motivated by a desire to ensure that other countries such as China and Russia do not make too many concessions to Iran during the negotiations.
