Calls for 5 Eyes Oversight - Opinion.
"The answer to that question lies much closer to home. The Five Eyes grew out of a UK-US agreement to share signals intelligence after World War II, a partnership which later expanded to include Canada, Australia and New Zealand. The members have since extended co-operation to include exchanging personnel and strategic assessments.
Like an omnivorous, 24-hour news organisation, the Five Eyes’ operations and facilities cover all time zones and continents, from listening stations at Pine Gap, near Alice Springs, to naval ships off Iran and satellite ground stations in the UK countryside, on top of the partnership’s hub, the National Security Agency, near Washington."
