Let's sy Bismarck ignores the pressure of the parties and the population and doesn't support colonies because originally he hated colonies. Would that also mean that Germany would probably not invest in the 2nd largest navy? If that means better relations with GB let's say that GB still joines FRance and Russia because lt's be honest, the whole "honor" that GB had to "protect" the poor Belgians from the "evil" Germans was a shitty excuse. They just feared german hegemony of Europe while they controlled 1/3 of the whole world. Anyways, so it's 1914 and WWI starts and goes like IOTL. Austrian Ultimatum, Russian mobilization Schlieffen Plan, GB joins after invasion of Belgium, but without colonies and probably a way smaller Navy would Germany have maybe conquered Paris?
