Sudetenland ,Austria,Poland,France........
it was all because of alliances, if there wasn't any peace treaty's between any of the countries in ww1 none of it would of happened, it would of been a war between Serbia and Austria-Hungary, but when Austria-Hungary attack Serbia Russia had to jump in to help Serbia and when Russia attacked Austria-Hungary Germany had to jump in to help Austria-Hungary, and then when Germany went to attack France through Belgium, BEF (Britain) had to jump in to help Belgium and France, and later during the war America and Italy joined in. Sounds a bit confusing but I'm sure its right :)
