"Strategy is about how nations use the power available to them to exercise control over people, places, things, and events to achieve objectives in accordance with their national interests and policies. The challenge for the strategist is to coordinate the various levers of national power in a coherent or smart way. Joint doctrine advises, 'Strategy is a prudent idea or set of ideas for employing the instruments of national power in a synchronized and integrated fashion to achieve theater or multinational objectives.' Ends--Ways--Means--Risk Methodology All strategies entail the same fundamental logic of ends, ways, and means. A comprehensive and effective strategy answers three basic questions:  Where do we want to go, or what are the desired ends?  How do we get there, or what are the ways?  What resources are available, or what are the means?  What are the risks and costs associated with the strategy?"
