They felt that it didn't resolve many of the problems that caused the Great War and that it unjustly punished the Germans (which helped set the stage for WWII); Allied leaders, US (Woodrow Wilson), UK (Churchill), France, Italy brought their ideas - Wilson's ideas were spelled out in the 14 Points (idealistic view of the post-war world, included international cooperation, self-determination or anti-colonialism, freedom of trade, creating the League of Nations, lasting peace through diplomacy and policing of bad actors, democracy globally begins to become an American ideal)
  • Nationalism - Nation-state formation leads to growing divisions and combativeness based on country identity.
