The long-running guerilla war in the Indonesian province of Aceh is finally over. Indonesian troops (other than those recruited locally) have been withdrawn, and the military wing of the Free Aceh Movement has been disbanded and disarmed. The pointlessness of this long war was brought home to both sides by the catastrophic tsunami a year earlier, which killed 170 000 people and forced everyone to co-operate in rescue and rebuilding.
Sadly, a similar impetus towards peace in Sri Lanka, appears to have faded. And of course the slaughter just goes on in places like Iraq and Darfur.
Overall, though, it’s Aceh that is representative of the trend. The number and severity of wars and conflicts has declined greatly since the end of the Cold War.
It would be a salutory effort to look over the wars, revolutions and civil strife of the last sixty years and see how many of the participants got an outcome (taking account of war casualties and so on) better than the worst they could conceivably have obtained through negotiation and peaceful agitation. Given the massively negative-sum nature of war, I suspect the answer is “Few, if any”.
