"Political scientists often argue that international economic relationships can decrease the likelihood that states will engage in war. Nations that might otherwise be inclined to fight can be deterred, informed or transformed by economic interdependence.
World War I has been called the “Achilles Heel” of such theories. In the decades before the war, Europe experienced unprecedented growth in international economic interdependence, both through trade and capital flows. Yet war not only broke out, but the scale of its destruction was unprecedented. Economic liberalism went into retreat. How could anyone sustain the notion that trade could prevent war when the most destructive war in history had followed an era of expansive international trade? For decades, scholars and policymakers alike pointed to World War I as providing strong evidence against the liberal case."
