He did nothing more than was done by X42. What's the problem?
The United States learned about the Chinese theft of the W-88 Trident D-5 warhead information, as well as about the theft of information regarding several other thermonuclear weapons, in 1995. A “walk-in” approached the Central Intelligence Agency outside the PRC and provided an official PRC document classified “Secret” that contained specific design information on the W-88 Trident D-5, and technical information on other thermonuclear warheads. The CIA later determined that the “walk-in” was directed by the PRC intelligence services. Nonetheless, CIA and other Intelligence Community analysts that reviewed the document concluded that it contained U.S. warhead design information. The PRC has the infrastructure and technical ability to use elements of the stolen U.S. warhead design information in the PLA’s next generation of ther-monuclear weapons. If the PRC attempted to deploy an exact replica of the US W-88 Trident D-5 warhead, it would face considerable technical challenges. However, the PRC could build modern thermonuclear warheads based on stolen US design information, including the stolen W-88 design information, using processes similar to those developed or available in a modern aerospace or precision guided munitions industry.
