It was on November 4, 1956 that 57 UN states voted in favor of Lester Pearson's idea of ​​creating a peacekeeping force to large scale. 1 This large-scale peacekeeping force would be known as the United Nations Emergency Force (UNEF) and would be tasked with ending the Suez Crisis. The idea was that British, French and Israeli forces would withdraw from the canal and that UNEF would remain in the canal zone to stabilize the situation. 2 The UNEF was responsible for monitoring the Suez Canal, facilitating the departure of Israeli, British and French forces, and maintaining peace between the opposing parties. A ceasefire was agreed on November 6, and UNEF forces arrived in Cairo on November 15. Thanks to Lester B. Pearson, the UNEF effectively managed to resolve the conflict between Egypt, Israel, Great Britain and France. Lester B. Pearson's idea was not Canada's only contribution to the Suez Crisis: more than 1,000 men and women were sent to Egypt as part of UNEF. Canada's role in the Suez Crisis was a critical point in Canadian policy and would reflect Canada's future role as one of the world's leading peacekeeping countries. Nuclear war was becoming a growing possibility, but the creation of UNEF led to the withdrawal of Israeli, British and French forces, which resolved the Suez Crisis. After the Israeli, British and French invasions, Soviet leader Nikita Khrushchev threatened to bomb Israel, Britain and France would have nuclear weapons if it did not withdraw its forces. It was at this point that the prospect of nuclear war became possible. At the time, the Soviet Union was seeking to strengthen its ties in the Middle East, so by entering the war in defense of Canada and Lester B. Pearson's success in preventing the outbreak of war, Canada gained a recognition and respect on a global scale and has become a major peacekeeping force. With the creation of the United Nations Emergency Force, Lester B. Pearson of Canada revolutionized the modern concept of peacekeeping, which led to the resolution of the Suez Crisis and at the same time, Canada has gained worldwide recognition and international stature. Thanks to UNEF, the Suez crisis was resolved. Had UNEF failed, nuclear war would have been a likely possibility. Canada's role in the Suez Crisis helped Canada become a middle power. Without Canada, more people would have died, more people would have lost loved ones, and more people would have suffered. Canada played a vital role in saving the lives of millions and saving the world from another war..
