This is patently false. Theme in pre-1914 continental European press was monarchies struggling with independence movements, question of next Franc-Prussian conflict (because everybody was certain that peace between those two can't hold), and stability of Russian empire (that was at time engaged in bloody war with Japanese while being shaken by internal tensions).
Inter-war period was hardly one of economical integration, considered that most of European countries were engaged in economic war with other - eg. Poland had no economic exchange with its neighbours.
Tensions were very high in early 20th century Europe. If you're honestly saying this you either have not read history books on the era, or you know something very scary about Merkel that I don't.
