So I am beginning to write my first TL's, and one of the main focus point's is a communist Germany, I seek to achieve this by having Bismarck not have the social reform's, and have a longer WW1. If anyone has a better suggestion or improvement, please say.
but anyway, I need a PoD which would stop Bismarck from putting them into practice, and since this is my first TL, I find myself unable to find one...
