What would avoid WWI? Shooting the entire German Staff. The Kaiser basically outsourced and allowed the Staff to play with Germany's foreign policy. It believed the only answer to any question was, "invade France!" The Schlieffen Plan was it and nothing else would do. An Austrian Arch-Duke gets shot in the Balkans, "invade France!" There is a dispute in Morocco? "Invade France!" There is trouble with Russia? "Invade France!" Everything was devolved down to one response - "Invade France!"
