Just read an interesting article on IEEE Spectrum about the mathematics of warfare.. more correctly the high level parameters that control how a war proceeds.
It's pretty long, but it essentially looks at how the US military was designed to combat a numerically superior force (Warsaw Pact) through advanced technology and intelligence... and how this fails when confronted by an "asymmetric war" (i.e. guerrilla war).
Two bits stand out in particualr:
"To the leaders of a nation with an overwhelmingly powerful military, every problem looks like it has a military solution."
Overall, one ruefully concludes that it is unlikely there is a military or a military-technical solution to the low-tech asymmetric warfare in Iraq.
Wonder how long it will take for our "leaders" to realise this.
