Review of FVEY, the spying, and the impact of DECLAS.
The Five Eyes was formally founded in the aftermath of the Second World War, through the multilateral agreement for co-operation in signals intelligence (SIGINT), known as the UKUSA Agreement, on 5 March 1946. Initially, compromising only the UK and the United States, it expanded to also include Canada in 1948 and Australia and New Zealand in 1956.
The FVEY agreements originated from military SIGINT and were initially used for the cold-war. Since SIGINT is the NSA’s primary mission, it would seem that most FVEY cooperation efforts with the US would involve the NSA, even though all the other IC members also have their own surveillance capabilities. I’m not clear on how Five Eyes operations are supposed to be authorized and approved, or what the chain of command would be. Based on the Q drops and other info, it appears to have been initiated/authorized at the WH, coordinated through the State Department (JK). The CIA used backchannels with UK and Austrailia to set up and perform the surveillance with spies from those countries (which explains the Brennan and Clapper’s involvement and their public attacks on Trump).
Alternatively, they just could have gotten their own rogue CIA/FBI agents to do the surveillance on the Trump Team and pretended to use FVEY as cover.
FISA DECLAS will reveal how it all happened, and identify many of the bad actors on both sides of the pond.
