The following links will take you to PME available online. This PME should give you the base line of education into what the nature of war is and what the current concepts within the joint force are.
The Clausewitz Homepage should be the beginning of your study of the art of war.
More academic sites will be added as I vet them.
Joint Doctrine and Concepts
Sustaining U.S. Global Leadership: Priorities for 21st Century Defense is what currently passes for a national strategy.
The Capstone Concept for Joint Operations: Joint Force 2020 is the Chairman of the Joint Chiefs of Staff vision of the joint force and how it will meet the priorities in Sustaining Global Leadership.
Joint Concepts: If there is a topic that you are considering discussing, make sure you look here to see if it has been covered before, and then improve on it.
The Air Sea Battle is a multi-service concept which attempts to explains how the Navy and Air Force envision operating in an advanced A2/AD environment.
Joint Doctrine: Please review the relevant doctrine before crafting your idea. You MIGHT find out that doctrine already has the answer, just no one around you bothered to read it. At a minimum, make sure that you understand the definitions in JP 1-02. If a word is undefined, then Websters Dictionary definitions are appropriate.
