A decisive Jutland could reshape alliances and naval treaties

In the decisive branch, Japan's shared wartime losses and Togo's service in Britain would make the Anglo-Japanese alliance harder to discard. If peace came before American intervention, the United States would retain financial influence through loans but lack the standing of a battlefield participant in the settlement. The counterfactual links those changes to the possibility of no Washington Naval Treaty. A decisive naval victory would also strengthen the case for naval power against calls to curtail it. The resulting choices over capital-ship construction could favour fast battleships and investment in larger facilities. Stronger wartime bonds would still leave room for later disputes over China, while Togo's British experience and an earlier Russian peace introduce further uncertainties.
