Answer:
Suez Crisis
Step-by-step explanation:
The Suez Crisis occurred in 1956 when Egypt nationalized the Suez Canal. This move was a cause of great concern for Britain and France, as the canal was a key transportation route for their oil supplies. The United States initially supported Britain's plan to use military force to retake the canal, but later withdrew their support and instead, worked with the United Nations to resolve the conflict diplomatically. The Suez Crisis created a rift between the leadership of the United States and the United Kingdom, with the US feeling that Britain's use of military force was unnecessary and that diplomatic efforts should be pursued instead.
