It does take two to tango, but only one to plunge the world into chaos.

I don't believe that the nations invaded by Austria and Germany in 1914 had any alternative but to defend themselves. I believe too that Britain's fifty-year legal, diplomatic, and moral obligation (shared with Germany) to defend Belgium from invasion, as well as its own self-interest in halting German aggression against Belgium and France, sufficiently justified its entry into the war.

Surely British interests were as obviously and immediately threatened by the German attack on France in 1914 as by Germany's later attack on Poland in 1939.

Passive resistance would have been of no use in either case.

But maybe it's just me....
