The book "Unrestricted Warfare" was written in 1999 by Qiao Liang and Wang Xiangsui, senior colonels in the People's Liberation Army of China.
("Unrestricted Warfare" was published in America with the subtitle "China's Master Plan to Destroy America" - which is simply sensationalist crap.)
"Unrestricted Warfare" touches upon the concepts of total war, multidimensional war, asymmetric warfare and expands them.
The way of thinking that wants more and more power reached its epitome with the possibility of nuclear war; simply overpowering and destroying the enemy does not work as a solution anymore.
The authors of "Unrestricted Warfare" raise important and perceptive questions: Who fights? Why fight and for whom? Where to fight? What means and methods are used to fight?
Traditionally, the answers would be: states, for political reasons, for the citizens, on the battlefield, preferably with superior means and methods.
In the world of today, such simplistic answers are not sufficient.
The authors introduce terms and concepts such as 'side-principal rule' and 'beyond-limits combined war', and support their thoughts with examples from recent history.
Presented in a clear and understandable manner, I find the ideas outlined in "Unrestricted Warfare" to be widely applicable on different subject matters.
