 In view of the cooperation between the Allies during the war, the decreasing reliance of Australia and New Zealand on the United Kingdom, and America's desire to cement this post-war order in the Pacific, the ANZUS Treaty was signed by Australia, New Zealand and the United States in 1951.This full three-way military alliance replaced the ANZAC Pact that had been in place between Australia and New Zealand since 1944.Australia, along with New Zealand, has been involved in most major American military endeavors since World War II including the Korean War, Vietnam War, Gulf War and the Iraq War—all without invocation of ANZUS.
