Here's another little matrix, which illustrates the flexibility of the War Paradigm - when it is applied correctly:

from 2009 Hartigan (thesis), Why the Weak Win Wars - A Study of the Factors That Drive Strategy in Assymmetric Conflict.pdf.

See also, 2007 Mauldin (thesis), Analysis of the Inability of U.S. Military Leaders to Provide an Adequate Strategy.pdf, who gets too carried away with the "Indirect Approach". BTW: the "indirect approach" (as used by Hartigan and Mauldin) is not vintage, pure Liddell Hart. It is more Andre Beaufre and others thinking independently.

The bottom line is that a "Strong Power" (e.g., USA) must be prepared to use both Direct and Indirect Strategies in what in actuality will be a mixed War and Peace Paradigm - the pure forms of those paradigms died a long time ago.
