I think it's not a solvable problem - at least not in any of the available frames. There are vested interests which find war much more amenable than peace would be, and even if - as usual - most of the local populations want peace, the leaders don't. Since rounding up the leaders and shipping them to Gitmo and/or the Hague isn't likely - here we are.

Besides, if someone blew up my relatives and starved them of food and medical attention I couldn't in all honesty say that I might not feel like killing them too. Violence will do that to people.

A modest proposal would be to move everyone out of the area and turn it into radioactive glass. With no more farcical claims to historical territoriality to argue over, everyone involved would have to start living in the 21st Century. Compensation could sweeten the deal. This would have the added benefit of making the heads of all of the Armaggedonites and fundies in the US explode - they'd have to find some other cranky and drugged-up biblical 'prophecy' to bounce up and down on.

Of course this isn't a practical solution, or even a humane one.

But it's frightening that it's likely to be more humane than any default alternative.
