Unrestricted Warfare is a book on military strategy written in 1999 by two colonels in the People's Liberation Army, Qiao Liang and Wang Xiangsui. Its primary concern is how a nation such as People's Republic of China can defeat a technologically superior opponent through a variety of means. Rather than focusing on direct military confrontation, this book instead examines a variety of other means. Such means include using International Law and a variety of economic means to place one's opponent in a bad position and circumvent the need for direct military action.
The book argues that the primary weakness of the United States in military matters is that the US views revolution in military thought solely in terms of technology. The book further argues that to the US, military doctrine evolves because new technology allows new capabilities. As such, the book argues that the United States does not consider the wider picture of military strategy, which includes legal and economic factors. The book proceeds to argue that the United States is vulnerable to attacks along these lines.
Alternative methods of attack
Reducing one's opponent, the book notes, can be accomplished in a number of ways other than direct military confrontation. The book notes that these alternative methods "have the same and even greater destructive force than military warfare, and they have already produced serious threats different from the past and in many directions for...national security."
Lawfare
, or political action through transnational or non-governmental organizations can effect a policy change that would be impossible otherwise. Because of the international nature of the modern world and activism, it is much easier for nation-states to affect policy in other nation-states through a proxy.
Economic warfare
Owing to the interconnected nature of global economics, nations can inflict grievous harm on the economies of other nations without taking any offensive action.
Network warfare
One of the better-known alternatives in this book is the idea of attacking networks. Networks are increasingly important in not only data exchange but also transportation, financial institutions, and communication. Attacks that disable networks can easily hamstring large areas of life that are dependent on them for coordination. One example of network warfare would be shutting down a network that supplies power. If there is a significant failure in the power grid caused by the attack, massive power outages could result, crippling industry, defense, medicine, and all other areas of life.
Terrorism
Another instance of threats to nations within the scope of the concept of "unrestricted warfare" is terrorism. Terrorism is used by a group to gain satisfaction for certain demands. Even if these demands are not satisfied, a terrorist attack can have vastly disproportionate effects on national welfare. One only has to look at the economic crisis that followed the terrorist attacks against the United States, or the extensive security measures put in place after those same attacks. Terrorism erodes a nation's sense of security and well being, even if the direct effects of the attacks only concern a minute percentage of the population.
Defense against unrestricted warfare
The authors note that an old-fashioned mentality that considers military action the only offensive action is inadequate given the new range of threats. Instead, the authors advocate forming a "composite force in all aspects related to national interest. Moreover, given this type of composite force, it is also necessary to have this type of composite force to become the means which can be utilized for actual operations. This should be a "grand warfare method" which combines all of the dimensions and methods in the two major areas of military and non-military affairs so as to carry out warfare. This is opposite of the formula for warfare methods brought forth in past wars."
Implications
As the authors state, the new range of options combined with the rising cost of waging traditional warfare results in the rising dominance of the new alternatives to traditional military action. A state that does not heed these warnings is in dire shape.
