Abstract
NATO's military strategy and doctrine have become one of the main references for Western strategic thinking and for the development of military strategy and doctrine in Spain. The Alliance's strategy started from a very specific scenario in the Cold War to expand after it towards a stabilization role outside Europe, and paradoxically return to the starting point afterwards due to the return of the Russian threat. Along this path, key concepts were developed on the use of conventional military power, nuclear weapons and new forms of asymmetric or hybrid conflict. Despite the fact that Spain entered NATO late and in a very peculiar way, NATO strategy and doctrine were essential to modernize both the armed forces and the strategic thinking in our country.
