For most of history, war has been a more or less functional institution, providing benefits for those societies that were good at it, although the cost in money, in lives, and in suffering was always significant. Only in the past century have large numbers of people begun to question the basic assumption of civilized societies that war is inevitable and often useful.

Now, for the moment, we are safe. The only kind of international violence that worries most people in the developed countries is terrorism: from imminent heart attack to a bad case of hangnail in fifteen years flat. We are very lucky people--but we need to use the time we have been granted wisely, because total war is only sleeping. All the major states are still organized for war, and all that is needed for the world to slide back into a nuclear confrontation is a twist of the kaleidoscope that shifts international relations into a new pattern of rival alliances.

The real requirement, if we are to avoid runaway global warming, is probably 80% by 2030, and almost no burning whatever of fossil fuels (coal, gas and oil) by 2050.

As the most religious country of the 18 surveyed, the U.S. also comes in with the highest rates for teen pregnancy and for gonorrhea and syphilis.

Take the year a country first reaches 50% literacy and add one or two generations to allow the idea to sink in and, democracy, more or less automatically, appears.

The military profession, especially in the long-established great powers, is deeply pessimistic about the likelihood that people and countries will behave well under stress. Professional officers are trained to think in terms of emergent threats, and this [climate change] is as big a threat as you are going to find. Never mind what the pundits are telling the public about the perils of climate change; what are the military strategists telling their governments? That will tell us a great deal about the probable shape of the future, although it may not tell us anything that we want to hear.
