American entry begins as a political problem before it becomes a naval one. In this scenario, British attempts to stop or impound cargoes bound for Japan create prize-court disputes and risks of confrontation at sea. Removing cargo and releasing a neutral ship follows precedents from the Napoleonic Wars and First World War, but repeated interceptions could still inflame opinion. The Asama Maru incident, when British action against a Japanese liner caused another crisis with Japan, supplies a close comparison. This alignment depends on the series' deliberately implausible domestic premise and does not claim that the historical United States was likely to choose that side.
