Steve,

There is no generalist theory of new governance that has ever shown any enduring value. Soup with knives, cups of tea, hearts and mind, money as a weapon, etc... do not create viable communities or community governances---ground truth shows the opposite. Never worked in any neighborhood any of you ever lived in, and never would. Why should it work anywhere else.
Are you implying we have such specialists in the military or even the government? Actually I suspect history will support the argument that specialists are academics and very ineffective in the real world. It is very much the generalist, or rather the individual leader who the people either willingly embrace or fear that enables the development of new governments. Most won't be overly effective whether designed by a specialist or a generalist, it is the nature of government to be somewhat ineffective.
