If an external force intervenes to give members of a community political self-determination, then that political community will almost surely fail to be truly free, since it is during the people' s struggle to become free by their own efforts that the political virtues necessary for maintaining freedom have the best chance of arising.

B: A community cannot remain free without first having developed certain political virtues.
C: Political freedom is a virtue that a community can attain through an external force.
D: Real freedom should not be imposed on a community by external forces.
