Britain outside World War I and German naval status

What if Britain never entered World War I?

Germany likely repeats something like the Franco-Prussian War, while the German navy loses status to the army even if it claims deterrent credit.

British neutrality offers Germany a short-term advantage but creates a long-term naval problem. A Franco-Prussian-style outcome on land leaves the German navy without the wartime role used to justify it. Naval advocates might claim that the fleet deterred Britain, yet its cost and purpose become easier to question. Any later Anglo-German war would also begin with a much larger British naval lead, though Britain might have fewer allies.
