Edward Feser, America, empire, and conservatism:

But imperialism is neither inherently immoral nor inherently unconservative, and it is false to assume that the fact that some American policy might plausibly be described as “imperialist” is ipso facto a reason for a conservative to disapprove of it.

Mr. Feser has not yet given a definition of imperialism, though one of the commentors has cited this definition: "the policy of extending the rule or authority of an empire or nation over foreign countries, or of acquiring and holding colonies and dependencies."

Is it possible to justly acquire authority over another nation or community? If it is just, is it always prudent?
