>>every time Germany feels economic anxiety they run out and invade six continents.
Six?!
Having just returned from the Alsace I can tell you that there are no real European borders any more, even with Switzerland, and kids have minimal interest in what the Maginot Line bunkers were about. If there's to be invasion I suspect it will be financial and cultural with France and Germany acting in concert and Britain enjoying another bout of standing alone.
"... They ne'er cared for us
yet: suffer us to famish, and their store-houses
crammed with grain; make edicts for usury, to
support usurers; repeal daily any wholesome act
established against the rich, and provide more
piercing statutes daily, to chain up and restrain
the poor. If the wars eat us not up, they will; and
there's all the love they bear us."
-- Shakespeare: Coriolanus, Act 1, scene 1
