You see, they swarm through an urban area, shoot out the transformers or short the wires with chain, turn on then break the hydrants eliminating water pressure, start interior fires in every building they pass. Hammer open the cash machines, load up on food from the markets, and entrap and decimate first responders, and then just keep moving. Amidst the chaos they empty the banks, and with sufficient numbers take the armories. It’s when they’re dramatic rather than practical that they lose. Now, they had a minimum of 30k men, and possibly a maximum of 200k men. What do you think would happen with one, two, or five million men? There are four hours of power, maybe three days of water, five to seven days of food, and without electronic transfers and distributions, millions of malcontents with pent up anger and ready violence to exacerbate the chaos. If men spread out into a small number of large groups in a series of cities it will take less than three weeks. Revolutions are always suspect in prospect but deterministic in retrospect. And those are just the revolutions that are unplanned. The era of state warfare is over. They have proven it. There has never been a civilization more fragile, and a government so weak.
