Report: NSA Spied on 35 World Leaders

Barack Obama won a Nobel Peace Prize for improving the global diplomatic atmosphere

Tensions between the U.S. government and its allies continued to flare amid reports that the National Security Agency monitored phone calls of 35 world leaders—this after Germany's government summoned the U.S. ambassador to account for allegations that the agency may have targeted Chancellor Angela Merkel's cellphone. 

The latest report in the Guardian says a secret memo reveals that the NSA was encouraging top departments to share their "Rolodexes" in order to keep numbers for top foreign leaders in their surveillance systems. The document reportedly said an official handed over 200 numbers, some of which covered 35 world leaders. Those leaders were not named.
