American Far Eastern interests complicate isolationism

The counterfactual explores several different pressures for American involvement in an Anglo-Japanese alliance. Its proposed public presentation as a defence of the free world is political messaging, and Japan's place in that description is explicitly questioned. Concern about an exclusive British-Japanese partnership could combine with national prestige, sympathy for Britain, or opposition to fascism. Opposition to a European war would not necessarily remove American interest in the Far East. The proposed route to wider cooperation depends on some opponents of European intervention deciding that participation would prevent Britain and Japan from arranging Asian affairs without them. Other isolationists would still oppose joining the war.
