Many attacks against USA are motivated because of actions like the ones from NSA. Other countries are starting to consider the USA an enemy to be defeated because bulshit likes this is getting shown.
If citizens of other countries start to make an outcry their leaders will make retaliations even if just for show.
> What really pisses me of is this sentiment of thinking of non-US citizens as second class humans.
When a group puts a draws a line of Us and them, they are making enemies. With this approach the NSA is declaring the USA as the enemies of all those being spied upon. The more similar news spread the more this mentality that "The USA is the enemy" will spread and its only a matter of time that more countries turn a blind eye or even facilitate terrorist actions against the USA.
