Your point from the edit is the most important point. I actually disagree with your views (that countries should not spy on a potential enemy's citizens), but I agree that the collusion of friendlies can have a catastrophic result for individual liberties. That needs to be clarified to be unlawful, if it is not intrinsically so due to the nature of the constitution of wherever you are living. If China wants the US to stop spying on its citizens, it can negotiate, throw up technological barriers, or declare war. Vice versa.
