Watch "Fareed Zakaria GPS," Sundays at 10 a.m. and 1 p.m. ET on CNN
On GPS this Sunday: The revelations over alleged tapping of German Chancellor Angela Merkel’s cell phone by the U.S. National Security Agency have strained relations between the two nations. But how serious are the current tensions? Fareed speaks with former German Defense Minister Karl-Theodor zu Guttenberg.
Next, the American side of the story. Who would have given the NSA permission to spy on leaders of ally countries? Former NSA and CIA chief Michael Hayden gives his take.
“[O]ccasionally, what you have is political guidance kind of being placed on top of your operational planning,” Hayden says. “I had political guidance while I was director of NSA. I had targets. I had legitimate needs. But I was told, frankly, back off. That target is too sensitive. I don't want you doing that at this time, for this purpose.”
And, New York Mayor Michael Bloomberg on his legacy as he prepares to step down.
