in the Snowden leaks, there was a GCHQ document about their policies for targetting US Persons using data shared with them from NSA. GCHQ is not allowed to indiscriminantly spy on US Persons. the document, marked classified as STRAP1, clearly orders GCHQ to apply US laws when targetting US Persons. which means "reasonable, articulable suspicion" before firing up XKEYSCORE and searching for everything a US Person has done in their life.
sadly, the reverse is not the same, since the UK has very weak privacy laws compared to the US. NSA can search for anything about any UK citizen without needing some form of probable cause. the Official Secrets Act and RIPA makes the UK into a quasi-dictatorship IMHO, which explains why we see the native population of the UK being so heavily subjugated by their Lords and Royals.
part of the SIGINT sharing agreement between NSA and GCHQ is that data will only be shared as long as these rules are enforced. so the myth that the FVEYS is a backdoor to circumvent the law and allow foreign intel to mutually spy on each other's domestic populations is a myth.
however, this assumes the FVEYS actually obey the rules in this document. how would we know if they dont? impossible for us uncleared civilians. for all we know, there are more layers of secret laws that allow FVEYS to ignore any and all of the checks and balances intended to limit their abuse of the SIGINT system.
that's the problem with secret laws. once you have them, nobody can trust anything about your entire legal system and you become a tyranny.

it has bothered me deeply that the UKUSA agreement itself was only declassified in 2013, most likely because of Snowden. keeping the existence of the FVEYS secret for 69 years does seem to me like an attempt to cover up treason.
pre-Snowden, when we talked about a Deep State existing at all, and when we quoted Rockefeller saying the world will be run by a supra-international clique of wealthy and politically powerful elites who transcend nations--the "Globalists", we were mocked as tinfoil hat wearing Conspiracy Theorists.

Treason against the United States, shall consist only in levying War against them, or in adhering to their Enemies, giving them Aid and Comfort
Foreign spy agencies, even of friendly countries, are our enemies due to their continual mission of attacking us with surveillance. But rather than working to defend the people against these attacks, NSA has chosen to conspire with the attackers!
