Gerson is an insider in the Republican power structure.  Correction:  Was an insider.  Trump does not bow to the same gods as Gerson.  Trump does not see America engaged in the perpetual foreign wars that Gerson and his ilk rely on to make money for the defense industry.  Gerson as assistant for policy and strategic planning for Bush would appear to be responsible for the Iraq debacle and other dark sides of policy in those years.  Yes, Trump repudiates partially the notion that the US should jump into wars around the world.  Thank God.  It is time to leave warmongering behind.
