Discussions about the nature of the ‘war’ the United States is presently fighting naturally requires a discussion on how we to fight the war. Understanding the right mixture of people, technology, military and police is critical. So is finding a balance between coercive pressures of economics, ideology (culture and religion), politics, and violence. It is like using the equalizer in iTunes. For some music, you push one slider up a bit and another down a bit and so on. For, say, gospel, the some or all of the sliders will move away, up or down, from where it would be for vocal or "spoken word" (audio books for example). Likewise, the sliders will move again when listening to Metallica. Each slider is independent of the other but yet they work best when operating in unison. This is what war is and has been like, and this is where Fourth Generation Warfare fails.
Remote and/or unattended warfare & monitoring is a field that will grow in importance and visibility over the coming years. Its impact on the composition and format of the US military over the next several decades will be substantial. Advances in technology may already be seen in the current UAV Roadmap of 2005 (PDF on GoogleDocs) that will be further strategized and propagated with the upcoming QDR that will be taking its “final shape” next week.
