Venezuela, Bolivia and Nicaragua have opened the door to granting asylum to National Security Agency whistleblower Edward Snowden in a standoff with the United States. The offers came after a plane carrying Bolivian President Evo Morales was forced to land in Austria after France and Portugal barred it from their airspace over false suspicions that Snowden was on board. The United States has refused to confirm or deny whether it was responsible. We discuss the latest with Guardian journalist Glenn Greenwald, who broke the NSA surveillance story based on Snowden’s leaks last month. In his latest scoop, Greenwald has revealed the NSA has systematically tapped into Brazil’s telecommunication network and indiscriminately intercepted, collected and stored the email and telephone records of millions of Brazilians for years. "The U.S. government has been its own worst enemy in this entire episode," Greenwald says. "The idea they would pressure their European allies to block the plane carrying a president of a sovereign state is a really radical and extreme act. It smacks of rogue nation status and the kind of imperialism and colonialism that Latin America has long chafed at. I think that’s the reason you’re seeing so much support for Snowden in Latin American governments and among the populations as well."
