According to a startling Pentagon video obtained by The Intercept, the future of global cities will be an amalgam of … urban hellscapes brutal and anarchic supercities filled with gangs of youth-gone-wild, a restive underclass, criminal syndicates, and bands of malicious hackers. At least that's the scenario outlined in "Megacities: Urban Future, the Emerging Complexity," a five-minute video that has been used at the Pentagon's Joint Special Operations University. All that stands between the coming chaos and the good people of Lagos and Dhaka (or maybe even New York City) is the U.S. Army, according to the video, which The Intercept obtained via the Freedom of Information Act. "Megacities are complex systems where people and structures are compressed together in ways that defy both our understanding of city planning and military doctrine," says a disembodied voice. "These are the future breeding grounds, incubators, and launching pads for adversaries and hybrid threats." A separate Army study published this year bemoans the fact that the "U.S. Army is incapable of operating within the megacity." These fears are reflected in the hyperbolic "Megacities" video. "Even our counterinsurgency doctrine, honed in the cities of Iraq and the mountains of Afghanistan, is inadequate to address the sheer scale of population in the future urban reality," the film notes.
