This isn't good. The Guardian, king of NSA leaks courtesy of that Snow guy, reports that the US has monitored the phone calls of 35 world leaders.
So, yeah, this is not good especially if a few of those presidents, prime ministers, and chancellors are allied nations. At the same time, I have to ask this question.
Surely, some of the intel agencies in these native countries, especially ones that we're friendly with, knew that we were and are actively engaged in monitoring communications outside of the US. And we probably even share intel with them.
I guess spy chiefs of these countries likely were in the know but couldn't exactly tell their heads of state about it.
