In “An American Empire! If You Want It instead of Freedom, Part 1”, Richard Ebeling quotes Garet Garrett on the symptoms of imperialism. “Second, domestic-policy issues become increasingly subordinate to foreign-policy matters.” But perhaps this was inevitable; foreign policy is the one field in which the central authority is most thoroughly exclusive under the US Constitution (power is shared with the provinces to some degree in most other matters), and so naturally ambitious politicians would tend to be attracted to it and favor it.
I’ll think about whether and how to address this problem in my new utopian constitution – when I’m not wearing my anarchist hat!
