Yeah discussing the afghanistan war goes a tad far here in this  
mailing list.

They did do a lot of things pretty bad there, from technical  
viewpoint seen.

If we see how much money DARPA threw into computerchess, with a part  
of that attention they gave it,
they could've saved lots of lifes of ordinary GI's in Afghanistan.

Let's for example just look at the powerbill and the thousands of  
CPU's thrown into battle from N*SA for parameter tuning....

But that's how society works.
