In a little under two minutes, Stratfor provides a succinct primer on 'France'. Its natural (ocean, river, and mountain) geographic 'barrier' borders, its major agricultural industry, and significant social cohesion. But, there is one weakness - the North European Plain - which remains France's main challenge - safe-guarding its north-European border, on the path of a historic invasion route. The most critical existential threat to France has come from its Eastern neighbor Germany and after three significant wars from 1871 to 1945, France attempted to 'contain' Germany largely through economic and political union. The most recent economic and political crisis (and the growing schism between Hollande and Merkel) suggest France's containment-strategy may be in question.
