"It turns out that perhaps the best way to beat guerrilla insurgents is by becoming one or, at least, funding one. Or, as John Robb argues on the Global Guerrillas blog, funding and partnering with many. The US military has slowly learned that traditional warfare won't beat "open-source insurgents," similar to how IBM has learned to embrace open source while simultaneously fighting it. Or, rather, to fight it on some fronts by embracing it on others. In warfare, as in software, the best way to fight insurgency may well to become part of it."
