US entry into the First World War in 1914-1915

How would the naval war and interwar period change if Theodore Roosevelt brought the United States into the First World War in 1914-1915?

US destroyers could contribute earlier, but a worked-up battle squadron would take until roughly 1916; the larger effect would be much closer Anglo-American naval relations after the war.

The panel cautions against treating American entry as an instant battle-fleet reinforcement. Destroyers and other light units could appear earlier, while compatible capital ships would need construction and work-up time before joining the Grand Fleet effectively. The more durable consequence would be deeper wartime integration and a closer Anglo-American naval relationship in the postwar settlement.
