"The mode of warfare is changing. State on state conflict is no longer the primary approach to war. A phenomenon known as Gray Area War is on the rise. Gray Area War is defined as a conflict where at least one of the antagonists is a non-state entity and the method is combining elements of traditional war fighting with organized crime. This method of warfare is eclipsing state on state conflict. The world is changing at an alarming pace. Alvin and Heidi Toffler outline the cause of these changes and attribute them to the Third Wave. The Third Wave is built upon the information revolution and globalization. The shrinking world is causing fractures and divisions in many states throughout the world. Not only are states in decline, but so is the mode of warfare that states traditionally wage. Though state on state conflict is [sic] decline, warfare will continue."
