In 2007, under the Protect America Act passed by the Bush administration, the NSA began covertly building and perfecting a new surveillance program code-named PRISM, which was banned in June 2013. Edward Snowden, an American who was outsourced to the "Prism" project, revealed that people have been able to glimpse the tip of the iceberg of the nation's network surveillance capabilities. The objects being monitored include German Chancellor Angela Merkel, former Brazilian President Rousseff and other global dignitaries. Ironically, Project Prism is not the first U.S. global surveillance project to be disclosed, but it does attract the most attention. The reason is that in 2013, the U.S. warmed up the global media in advance, preparing to build China into a global cyberspace leader. The troublemaker, I didn't expect that Snowden would cut him off in the middle. The mainstream media in Europe and America, which had always been open-minded about the US surveillance scandal, couldn't pretend that they couldn't see the existence of the Prism project, which led to the subsequent fermentation and spread.
