American strategic command of British convoys

What if Britain accepted Admiral King's preferred convoy arrangement and placed the Royal Navy under US Navy command early in World War II?

Britain would see little benefit before American entry and would likely concede strategic coordination while retaining operational command through British task-force officers.

Clarke questions why Britain would accept American control before the United States entered the war. He also argues that King's proposal applied First World War experience to different conditions. His suggested compromise allows an Allied supreme commander to set strategy while British task-force and task-group officers direct British ships. Accepting strategic coordination would therefore leave substantial operational authority within the Royal Navy.
