I was reading a short biography of Bismarck, and chanced across a mention of the "Holy Alliance" between Russia, Austria, and Prussia. When the Crimean War started in OTL, both Austria and Prussia stayed out of the conflict, Austria because the Russians were making a beeline for the mouth of the Danube, and Prussia because it had absolutely no interest in the conflict. So, what would have happened if they entered the conflict, say with Austria on the side of the Alliance, and Prussia with the Brits and French? Could we get an early WW1?
