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."
