A quick google on this shows around 4500 results so I know this is a well explored topic. However I couldn't find anything quite like the question I wanted to ask here.
Reading in particular Margaret McMillan's book Peacemakers as well as othe contemporary accounts like Keynes' The Economic Consequences of the Peace, it seems to me that while there are a myriad of different possible outcomes to the conference in terms of Treaties and political geography I can't see any of them being much better than any other. The range of enmities, tribal rivalries and realpolitik at work suggests that in practice we would have had some sort of major conflict around the same time as OTL WW2. The parties might be different, the seat of the conflict might vary, but somewhere in Europe all hell breaks loose.
So - my question is this. Can anyone identify an outcome or outcomes that would not lead to major conflict in Europe of some description?
