In 2007, Johns Hopkins School of Advanced International Studies sponsored and hosted a symposium on unrestricted warfare. Marine Corps Officer David Nass called the book “a provocative vision for what irregular warfare, omnidirectional warfare, or multi-domain warfare could look like in the early 21st century.” U.S. Air Force Nuclear and Missile Operations Officer Dallas Tueller wrote in Small Wars Journal that Unrestricted Warfare “highlights China’s long-term strategic vision.” It is, they write, “warfare which transcends all boundaries and limits; in short: unrestricted warfare.” The breadth of the authors’ vision of unrestricted warfare is brought home by this stand-alone paragraph from the book:Atomic warfare Diplomatic warfare Financial warfare Conventional warfare Network warfare Trade warfare Economic aid Bio-chemical warfare Intelligence warfare Resources warfare Ecological warfare Psychological warfare Economic aid warfare Space warfare Tactical warfare Regulatory warfare Electronic warfare Smuggling warfare Sanction warfare Guerilla warfare Drug warfare Media warfare Terrorist warfare Virtual warfare (deterrence) Ideological warfareSome of these types of warfare are not new, others are.
