No, governments have and will do whatever is possible to commit act of wars against any country to serve its own interest. But the issue is that in this digital era, the power that governments exercise is exponentially larger than in the past and the room for potential abuse has also grown substantially with it. History has show that even with little power (as compared to now), many great awful things have been done.

Things get progressively worse and people get used to them. Today it has been revealed that all our communication channels are tapped. People will make arguments that they have nothing to hide and even if not, they will soon forget and learn to live with it. Tomorrow, governments around will ask for your fingerprints and retina scans (this is already happening in India). People will meh and get over it. Then they will install cameras everywhere and try to track all your movements. Given the amount of electronics surrounding us, cameras would be just another in heap and people won't budge. We are technologists and we know that though hard, these things are possible to implement at a national level.

You said that the solution is to ensure that good people are elected. It is very much important to do that asap. The system is turning more opaque every second. As governments accrue more power over the lives of citizens, it will harder to take govt down if things go wrong. Snowden did what is defined as "illegal" but the law is wrong in the first place. People are moaning over the internet that what NSA is doing is unconstitutional but has it achieved much yet? Petitioning the White House isn't probably going to get any proper answer. NSA didn't ask people whether they were OK with such surveillance, it was all decided behind closed doors. Even in a system where you can openly ask representatives and govt about its actions and they are not answering, so just think of the future when questioning the government's motives will land you a red ticket.

I am genuinely worried.
