I think all Western nations have actually fallen a helluva long way since the Greatest Generation. We talk like we are our grandparents. I've got news for you - we ain't. I'd say pretty much ever Western nation, as it stands now, is best thought of as being France in early 1939. Full of that over-confident 'it could never happen here' false-sense-of-security. I think some of the Western, particularly the Anglo-descended ones (USA, Canada, Australia, and NZ), are kidding themselves.
I'm Australian - look around at the people you see everyday - they aren't fighters. The whine and complain about *everything*. These are not the kind of people I would expect to pull out an assault rifle, yell "Wolverines!!" and start blasting away at an approaching Hind. Hell the vast majority of Aussies wouldn't know how to fire *any* gun let alone *hit* anything.
Aussies have this silly image of themselves as rugged, manly types. If an army invaded, the majority of us would accept the surrender just as the French did. We simply aren't prepared, mentally or para-militarily.
