Terrorism is not a weapon that is used by the weak, but also by strong nation states. However, the way that terrorism is used by stateless organizations is as a weapon of strategic unconventional warfare. It is a strategic guerrilla warfare when you think about it, except that guerrilla warfare is unconventional tatical warfare used against superior, organized military force. Terrorism is unconventional strategic warfare used against a strong or powerful nation. A book about Bin Laden which some CIA members who were part of the Bin Laden Unit commented on, said that Bin Laden's unconventional strategy against the US was to bankrupt the US economy by attacking high value targets that if destroyed, would do great damage to the US economy and to demoralize the US by striking and destroying powerful moral and economic symbols of the US. Ultimately, Bin Laden's unconventional approach is to strike the US from the shadows and to hit economically high value targets while at the same time creating a spectacular psychological impact on the US, part of the psychological as well as economic warfare against the US.
