RESEARCH: Georgetown students shed light on China’s tunnel system for nuclear weapons. “Led by their hard-charging professor, a former top Pentagon official, they have translated hundreds of documents, combed through satellite imagery, obtained restricted Chinese military documents and waded through hundreds of gigabytes of online data. The result of their effort? The largest body of public knowledge about thousands of miles of tunnels dug by the Second Artillery Corps, a secretive branch of the Chinese military in charge of protecting and deploying its ballistic missiles and nuclear warheads.”

UPDATE: Payback? Heh.
