Additionally, the politicians who are calling for trade agreement cancellation are doing so on the stage of the world – with specific political agenda. They do that because if they don't, they invite exploitation and will lose their own power.
The revelation of all the facts about the reality of the power structures in the world must occur, and it must occur so that the people can finally live without latent animosity towards each other. The fact that the surveillance was not leaked with documents via a publicly accepted media outlet before Snowden does not somehow mean that the problems did not exist before and have continuous affect on people, society, and further, the world. On the contrary, as long as people live in ignorance or denial of important problems, it means those problems are hidden by the society, and the society will become dark and the society in turn causes people to do wrong things.
In a dark society, justice becomes lost. When justice is lost, the society will fall. That's why this effort to reveal the reality has quite the opposite effect on our society of harming us. It is absolutely necessary if we are to survive the next decade and if we are to truly live with worldwide cooperation.
I'm not oblivious to the intelligence services here in Europe, although their focus hasn't exactly been the US. I'm aware of the political shenanigans, and of course they're trying to exploit the situation to their own benefit. As a European I'm furious, but right now I don't care about internal politics. I care about external threats, since that's what the USG just demoted their own country to.
I love the States, but it's a tough love right now.
