Explanation
The Suez crisis was a military conflict developed in Egypt in 1956. In this conflict, the military alliance formed by the United Kingdom, France, and Israel fought against Egypt supported by the Arab League. This conflict originated because the Egyptian government wanted to nationalize control over the Suez Canal that had been under the control of France and the United Kingdom. For their part, the United States and the Soviet Union opposed this intervention because it threatened their political and economic interests, so the United States requested the withdrawal of the allies, and the Soviet Union threatened to use weapons of mass destruction on the capital cities of England and France. From the above, it can be inferred that in the Suez crisis that the great powers of the moment managed the world under their interests and wanted to keep power balanced between the two of them.
