Reporting from Beirut As protesters poured into the streets of Iran in the aftermath of the disputed 2009 reelection of President Mahmoud Ahmadinejad, U.S. diplomats scrambled to decipher the erupting political crisis and the goals of the opposition's so-called green movement, according to recently disclosed diplomatic cables. The diplomats hurried to understand without the benefit of an official outpost in Tehran, a result of the 1979 Islamic Revolution. Instead they read news bulletins and spoke with allied embassies in places like Azerbaijan, Turkmenistan, Turkey and Dubai, United Arab Emirates. They contacted Iranian dissidents, human rights activists and disgruntled businessmen, according to the confidential dispatches made public in recent days by WikiLeaks.
