Although you do not specify what canal you are referring to and the time in history, we can assume that you are referring to the Suez canal crisis.
If that is the case, the correct answer is false.
No, the United States was not consulted by their allies on the plan to take back the canal, and that caused too much trouble in the so-called Suez canal crisis.
Egyptian President Gamal Abdel Nassar had nationalized the canal and Israel troops were immediately sent in October 1959 to attack Egypt. Sooner than later, the French and Great Britain supported Israel and that made the Union Soviet intervene to solve the conflict, a thing that upset the United States that lived a permanent tense situation with the Soviet Union during the Cold War years.
