It would be a great pity if change had to be contingent on the continuation or necessity of war. But I suppose that would only be so if the 'shift' were to be unplanned. ... or do I mean unforeseen... or more likely have I missed the point! Let's hope sam is right and war is only one sort of change. Thankfully there are others.

But then maybe shifting to Type One is not desirable?

NB. Thanks for the explanation Zephir. It helped.
