What if Dogger Bank diplomacy failed and Britain and Germany entered the Russo-Japanese War on Japan's side?
Short answerRussia's fleet is rapidly destroyed, France may intervene, and the conflict risks becoming an early world war fought across Russia's fragile logistics.
NotesThe Russian fleet would face overwhelming naval opposition from the Channel Fleet and Japan. France might intervene to prevent its ally's collapse, turning the crisis into a proto-world war. Russia's land position also worsens because the Trans-Siberian supply line must support war against Japan while Germany threatens from the west. British attacks on Russian merchant shipping would add another pressure on a state fighting at opposite ends of its territory. The result is expected to be an early peace or a much wider collapse, depending on how France and the other powers respond.
