A delayed First World War with Britain and Italy neutral

Which delayed-First-World-War alignment would be most interesting?

The proposed scenario puts France and Russia against Germany and Austria-Hungary, with the other major powers neutral.

A war delayed to 1920 could begin with a Balkan crisis that puts France and Russia against Germany and Austria-Hungary. In this scenario, continuing Russian pressure around India helps pull Britain away from the Franco-Russian alignment, while Italy's disagreements with its allies keep it outside the conflict. Britain, Italy, and Japan remain neutral, and the discussion also places the United States outside this narrower war. Germany would face a modernized Russian force, although failures of Russian land command could still affect the outcome. British or Italian intervention would depend on whether either government saw an advantage in entering.
