Such a forecast was part of an analysis of the weaknesses of the American military system by two Chinese military planners, who also identified Osama bin Laden as one of the likely perpetrators of a possible attack.
The officials, Qiao Liang and Wang Xiangsui, who were in service at that time, made the forecast in the book "Unrestricted Warfare" written in 1999, which has now beenpublished in India, several years after being translated into English for the CIA, the Defense Intelligence Agency and other US national security departments.
The officials, who were then senior colonels, said:
"Actually, with the next century having still not yet arrived, the American military has already encountered trouble from insufficient frequency bandwidth brought on by the above-mentioned types of enemies.The US was an area of major focus in the book, which proposed tactics for developing countries like China and measures to compensate for their military inferiority vis-a-vis America in a possible hi-tech war.
Whether it be the intrusion of hackers, a major explosion at the World Trade Center, or a bombing attack by Osama bin Laden, all of these greatly exceed the frequency bandwidths understood by the American military.
The American military is naturally inadequately prepared to deal with this type of enemy psychologically, in terms of measures and especially as regards military thinking and the methods of operation derived from this."
