I am glad for any document that has been leaked. Although we might not be able to see the whole picture yet it made one thing clear: the US government is at the same moral level as countries like Russia, North Korea or the Iran to me. They do neither respect the privacy of their citizens nor the privacy of any other person in the world. They might have some moral concepts that are a little bit more close to mine as a European (aside from the gun laws, death penalty). The problem is that they have much more power and influence than any of these countries.
What kind of idiot would ever want to stand on the wrong side in this world? We see that communication is not private, maybe every technical device could be used to spy on you and in a war against the USA you would not even see the enemy's soldiers. THIS is a reign of terror.
