"In the first place, this is a history of Europe's reduction. The constituent states of Europe could no longer aspire, after 1945, to international or imperial status. The two exceptions to this rule--the Soviet Union and, in part, Great Britain--were both only half-European in their own eyes and in any case, by the end of the period recounted here, they too were much reduced. Most of the rest of continental Europe had been humiliated by defeat and occupation. It had not been able to liberate itself from Fascism by its own efforts; nor was it able, unassisted, to keep Communism at bay. Post-war Europe was liberated--or immured--by outsiders. Only with considerable effort and across long decades did Europeans recover control of their own destiny. Shorn of their overseas territories Europe's erstwhile sea-borne empires (Britain, France, the Netherlands, Belgium, Portugal) were all shrunk back in the course of these years to their European nuclei, their attention re-directed to Europe itself.
