Conventional Western (mainly American) concepts of war are incompatible and fundamentally misaligned with the realities of war in the twenty-first century. The emergence of a unipolar post-Cold War world order has resulted in a significant paradigm shift.
This change now requires the U.S. and its allies to adopt a new legal, psychological, and strategic understanding of warfare and use of force, particularly by state actors.
The term “hybrid war” (military institutions use the term “hybrid threat”) connotes the use of conventional military force supported by irregular and cyber warfare tactics. In practical application, the Russian concept of “nonlinear conflict” exemplifies hybrid warfare strategy.
