I view this question as an obvious troll of the board. Even withstanding that, the question itself is overly broad. Text books, curriculims, even entire colleges (e.g. military service colleges) are written or established to review the value and measures of War. This isn't a question that can be handled well in the SE format, as evidenced by the answers it gathered before being put on hold.
Given its troll nature and an existing vote to re-open the question, without any effort to narrow the scope, the question should be deleted out right.
