The only effective solution to the problem of "NSA and the ability of the US government to override any treaty to access any data" is the furtherance of study, and application of Homomorphic encryption. Homomorphic encryption is a type of encryption done on data, and sent to a remove server (cloud), and the data is processed in an encrypted form. It never is unencrypted during any part of processing. And when it is transmitted back to the originator, they can decrypt when they choose. Unfortunately, right now the speed is very slow, but work in this area can allow all sorts of data to be processed in the cloud securely.
