Does any serious person seriously think that the European Continent is again going to be divided up into a score of sovereign nations, each with its independent border guards, tariffs, export restrictions, currencies, forts, armies, bureaucracies … ? I doubt that anyone really thinks so. If it didn’t work after Versailles, when conditions were a hundred times more favorable, when mounting mass unemployment and permanent economic depression were not yet inescapable features of capitalism, it is certainly not going to work today or tomorrow.
