A very interesting discussion with Dr Bell. The world didn't suffer a M.A.D.-style nuclear war, thank goodness.
But surely you should count in:
We tend to remember the US & Australian dead, but there were millions of North & South Vietnamese, plus 'collateral damage' in nearby countries.
These regimes were propped up by one or the other side, many were simply the usual "strongman" dictators that infest human history, but they used the rhetoric of one side or the other to get support.
Again, one side would appeal to the USSR or China as fighting the oppressive government and the other would then appeal to the US to oppose the left-wing guerillas (or vice-versa), even tho' examination could show neither side was anything much more than fighting for power in the dirtiest of ways.
Yet again, like terrorism & reaction against it today, the cannon-fodder troops could be recruited by ideology or religion as well as force, whether or not this coincided with the leaders' true beliefs.
I wonder if adding these up you'd get to 100 million (100,000,000), the figure she mentioned if the Cold War got hot -- which would also kill more over the years following, and devastate the natural world.
Alas, these casualties seem to be continuing quite unabated, as the heralded "Peace Dividend" is sucked back into armaments, rather than advancement, and "other people" are again painted black or white like chess pieces to be shuffled around the board instead of fellow humans to be dealt with on their merits. And the world beyond humans? Just a battlefield & mine for resources, instead of a living & beautiful home.
I miss Barbara Tuchman's incisive analysis, shown in work like her "March of Folly" - a book I'd highly recommend for today's world, as well as of course Coral Bell's :)
