Though force is the most effective instrument for seizing power in a society, and though it always remains the foundation of any system of inequality, it is not the most effective instrument for retaining and exploiting a position of power and deriving the maximum benefits from it.  Therefore, regardless of the objectives of a new regime, once organized opposition has been destroyed it is to its advantage to make increasing use of other techniques and instruments of control, and to allow force to recede into the background to be used only when other techniques fail (1966, p.51).
