Skynet- death from above

From stratosphere to exosphere, the Pentagon is now producing an armada of fantastical new aerospace weapons worthy of Buck Rogers.

By 2025, the United States will likely deploy advanced aerospace and cyberwarfare to envelop the planet in a robotic matrix theoretically capable of blinding entire armies or atomizing an individual insurgent......the Pentagon apparently hopes to patrol the entire planet ceaselessly via a triple-canopy aerospace shield that would reach from sky to space and be secured by an armada of drones with lethal missiles and Argus-eyed sensors, monitored through an electronic matrix and controlled by robotic systems.
