I wonder how the air war during WW1 would have gone, had in the late 1890s Wilhelm II told Tirpitz we don't need to antagonize the British by building a battlefleet. Instead, let's follow the examples of our Baltic and Dutch cousins and focus on coastal defence vessels, plus protected cruisers for our colonies. And now, instead of a battlefleet, let's focus on building the strongest economy and advanced engineering and manufacturing industry in the world, 2nd only to the US. Oh, and build the largest and most technologically advanced army in the world so that if the time comes, we can roll over France and Russia… but to keep our British cousins happy, always stay out of Belgium. By the 1910s this would have led to the Germany's introduction of warplanes. In 1914 when France and Russia declare war, the Luftwaffe might not have to face the RAF at all.
