If events of the past six years, or 25... 50... 100 or even 200 years have taught us anything it is that it doesn't matter how well you have informed yourself as a nation. Or armed yourself. Or how rich you are. Even a very small band of individuals determined, or inspired, or desperate enough can bring you to your knees, sometimes by the simplest of means.
Sometimes one person, with enough grit and spontaneity, can stop a tank or release secrets that bring a government to a halt, if only to be exposed to the world for its excesses. Sometimes cunning and stealth are greater than superior strength or mass or numbers.
