Meaning of STRATEGY in English

In warfare, coordinated application of all the forces of a nation to achieve a goal.

In contrast to tactics , strategy's components include a long-range view, the preparation of resources, and planning for the use of those resources before, during, and after an action. The term has expanded far beyond its original military meaning. As society and warfare have steadily grown more complex, military and nonmilitary factors have become more and more inseparable in the conduct of war and in programs designed to secure peace. In the 20th century, the term grand strategy, meaning the art of employing all the resources of a nation or coalition of nations to achieve the objects of war (and peace), steadily became more popular in the literature of warfare and statecraft.
