Don Rumsfeld's leaked memo ("Are we winning or losing the Global War on Terror? Is DoD changing fast enough to deal with the new 21st century security environment?") has got a lot of people asking if the Pentagon has any idea what it's doing. As the US military is, in and of itself, a major driver of world events, those trying to steer global change need to know how the military mindset evolves. Here are two key resources:

Pentagon's New Mapdetails the theories of Thomas Barnett of the naval War College that the less connected (to the global economy, international agreements and the Internet) a place is, the more likely it is to become an enemy of the United States. Draw your own conclusions.

John Arquilla's The Advent of Netwar is an extremely influential examination of the future of war. How does "low intensity warfare" change when the enemy is networked "terrorists, criminals, fundamentalists, and ethno-nationalists... revolutionaries and militant radicals," and how does the military adapt to fight them? Again, make up your own mind.
