The confusing part is, if the war was ended indecisively then how is that going to prevent future wars? Brush fire wars plagued Europe for centuries until WWII came about and everybody realized that war was too dangerous to toy with anymore.

The people might have been different, but I don't see how an indecisive WWI prevents another border skirmish from getting out of hand 20 years later. Maybe it would have been better for the Jews, but even that's iffy given the generally hostile attitudes of continental Europeans to Jews and Gypsies.
