We often mention in WWI topics the entangling alliances that would have resulted in a world war even if Archduke Ferdinand survived. How could this have been prevented, and bonus points if you can think of a plausible solution with a POD after the Franco-Prussian War? Would Bismarck have to be removed from the picture, or would continuation of his foreign policy be the correct route? Could the Balkan situation have been resolved more peacefully? Is Lenin's basic idea that WWI was the result of the European countries turning on each other after running out of African and Asian colonies to plunder correct, or was it just another form of communist propaganda? If I haven't addressed any major scenario here, please feel free to bring it up.
(You CAN use an After 1900 POD if you want; I just posted it here because there seems to be a wider range of possibilities in the Before 1900 forum)
