After watching a debate on youtube on the subject, I became intrigued with this scenario. If Britain had stayed out of the war, could the Schlieffen plan have worked? It seems likely that the central powers would've won the war. What would the public opinion in Britain be like. Would people be in favour of a new German dominated Europe? Would the Bolsheviks still rise to power? I think this would be a good twist to the popular, What if the Central Powers won WW1? trope.
