The most interesting aspect of this disclosure is the 1993 annexed memorandum, which describes the ongoing operational review of the UKUSA agreement by the Operations Directorate. First, “there is not a single document detailed enough to serve as such an agreement,” which confirms to some extent the description of the evolution of the UKUSA agreement in the 1985 document discussed above. Second, it acknowledges that “listing what Daesh shared would be extremely costly in terms of the hours of man needed.” It therefore proposes to “divide the task into three parts”, which consists of “exchanging in sufficient detail the things that are not exchanged today with the United Kingdom (in good conscience), “the things that managers and high-level technical experts think they need to change or be declared irreversible in the near future (5-8 years or less). and (3) “the new things that should be exchanged with the United Kingdom in the future.” Another SIGINT agreement between Canada and the United States was signed in 1950 and created the joint high-frequency research network of the Royal Canadian Navy and the United States Navy.  It is likely that there are also dozens of less bilateral agreements and declarations of intent. Finally, the “Fund” section indicates that the nature and scope of the agreement between the NSA and GCHQ are also extended to third countries. The agreement provides that the two partners will enter into an agreement on COMINT`s relations with third parties and ensure that material obtained under such agreements by third parties is made available to GCHQ and the NSA. “Canada, Australia, New Zealand and not considering as third parties” has been the subject of “special attention.” (This particular consideration is documented in Appendix J of the 1955 version of the agreement and leads to what we know today as a five-eyed alliance.) He added: “As the threat of Nazi Germany was replaced by a new one in the east, the agreement served as the basis for intelligence cooperation during the Cold War. The two nations, associated with common links of history, culture and language, agreed not to gather information against each other or to inform a “third party” of the existence of the agreement. The details of the NSA`s agreement to share the personal data of U.S. citizens with UNSI. New Zealand is still an active member, although in 1985 the United States deferred its obligations to that nation under the DEEE Treaty and declared it “a friend, not an ally.” The so-called failure of the Cambridge Five secret service in Britain in the early stages of the Cold War stifled the American faith, but Britain was not excluded from the group.
More recently, Edward Snowden`s revelations have revealed a flood of compromising Western intelligence services, many of them on the Five Eyes. Instead of hindering the creation of the alliance, Snowden`s leak effectively prompted the group to emerge from the shadows and public opinion, with widely reported annual meetings and joint communiqués. To support the history of the NSA agreement, the memorandum adds a 1945 memorandum from President Truman authorizing the then Minister of War and the Secretary of the Navy to “continue cooperation in the field of communication between the U.S. Army and the Navy and the British and to extend, modify or terminate that cooperation. , or because it is determined to be in the best interests of the United States. This Presidential Memorandum is of particular interest because it provides evidence that the President directly authorized the various military branches to determine the course and future contours of the UKUSA agreement.
