John McAfee, American computer programmer and contributing editor of Business Insider, explains how the NSA's back door has given every U.S. secret to its enemies. He begins by mentioning the importance of software, specifically meta- software, which contains a high level set of principles designed to help a nation survive in a cyberwar. Such software must not contain any back doors under any circumstances, otherwise it can and may very likely allow perceived enemies of the U.S. to have access to top-secret information. For example, the Chinese used the NSA's back door to hack the Defense Department last year and steal 5.6 million fingerprints of critical personnel. "Whatever gains the NSA has made through the use of their back door, it cannot possibly counterbalance the harm done to our nation by everyone else's use of that same back door." McAfee believes the U.S. has failed to grasp the subtle implications of technology and, as a result, is 20 years behind the Chinese, and by association, the Russians as well.
