Yes, if they are not spying on OTHER countries in the agreement, what that actually means something worse: The five countries are actively spying on their own people if they are respecting the agreement, Constitutions be damned. Because modern governments are going to spy on everything they can. We already know FBI agents used domestic spying infrastructure to stalk women and mistresses and ex-wives. That level of casual use means there is a 99.9999% chance it is used by the government for tracking journalists, leakers, liberal activists (but not right wing ones), profiling uppity citizens, etc. If facebook and internet ad companies have complete information on you and your associates and post history and beliefs and location, the government has it. Multiple government have it. We're already running shameful (Obama and Trump) concentration camps for immigrants (aka "lesser" humans), have detained US citizens as enemy combatants, performed extrajudicial assassinations on US citizens overseas, have two gestapo departments (Immigration Customs Enforcement and Customs Border Patrol) with radicalized right wing membership in their ranks. All it takes is a charismatic strongman (probably from the right but can be from the left too), a false flag event like Gulf of Tonkin, do McCarthy hearings in Congress to stoke fear of external enemies within us, and start rounding up people. The US could turn into a fascist regime in record time aided by complete IT awareness, soon with AI for profiling and analysis, AI agents for complete propaganda, and all the legal, historical, and dirty pool history to enable it.
