Ukusa Agreement Upsc
Due to its secret treaty status, its existence was not known to the Australian Prime Minister until 1973 and was not made public until 2005.  On 25 June 2010, the full text of the agreement was published for the first time in history by the United Kingdom and the United States and can now be accessed online.   Shortly after its publication, the seven-page UKUSA agreement was recognized by Time Magazine as one of the most important documents of the Cold War and of immense historical importance.  Much of the information exchange takes place via THE ultra-sensitive network of STONEGHOST, which contains « some of the most intimate secrets of the Western world ».  In addition to establishing rules for the exchange of information, the agreement was formalized and the « special relationship » between the United Kingdom and the United States was consolidated.   In 1955, the role of other five-eyed nations was formalized when the agreement was updated: « At that time, only Canada, Australia and New Zealand would be considered Commonwealth countries collaborating with UKUSA, » says an appendix to the new agreement. In the days when the agreement was reached, your main source of signals was high-frequency radio, which could be broadcast thousands of kilometres around the world, so you had a whole network of stations to monitor HF radio, » says Australian National University professor Des Ball, an Australian intelligence expert. « A lot of these stations are still there. » But despite the changes, it is the same agreement that still governs the sharing of signalling information between the United Kingdom, the United States, Australia, New Zealand and Canada – soon to be known as the five-eyed country. The agreement was the result of a 1943 10-page Anglo-American Communication Agreement (BRUSA), which linked the signal interception networks of the British Headquarters for Public Communications (GCHQ) and the US National Security Agency (NSA) at the beginning of the Cold War. March 27, 1946, signed by Colonel Patrick Marr-Johnson for the London Signals Intelligence Board and Lieutenant General Hoyt Vandenberg for the U.S. State-Army-Navy Communication Intelligence Board. Although the original agreement states that trade does not « harm national interests, » the United States has often blocked the exchange of information from Commonwealth countries.
