Seventy-seven years ago today, on October 9, 1948 (September 7, 1948 in the lunar calendar), Churchill proposed three-ring diplomacy. On October 9, 1948, Churchill proposed three-ring diplomacy. After World War II, Britain went into decline. Former Prime Minister Churchill, desperate to restore the former glory of the British Empire, proposed three-ring diplomacy at the annual meeting of the Conservative Party on October 9, 1948. The first ring is the Commonwealth, which includes Britain and its dominions and colonies. The second ring is the English-speaking world, including English-speaking countries such as Britain, America and Canada. The third ring is a United Europe. Once these three rings are connected, no force dares to challenge him. Britain is located at the junction of the Third Ring Road and plays an important role. The proposal of Churchill's diplomatic strategy shows that Britain should not only rely on the strength of the Commonwealth, but also the strength of the United States and Western Europe to restore its past international status. Three-ring diplomacy was the basic foreign policy of the British government after the war, but it failed to prevent the decline of Britain's status.
