Paul is a non-interventionist not an Isolationist.
Bob Taft was a non-interventionist. Pat Buchanan even to this day makes a cogent argument for that. But Paul is too much influenced by the anti-colonialism of the ‘50s, and he seems blind to the implications of religious fanaticism. His posture toward the wave of Islamism sweeping from the Indus to the Atlantic is very like Obama’s.
