The Principle of Universality

By which what is right for us is right for others, and what is wrong for others is also wrong for us. John McCain’s rejection of this principle, though it’s couched (unconvincingly, not to mention Orwellianly) in terms of acceptance by completely redefining the principle to mean its exact opposite, puts him on the aggressive end of mainstream elite opinion on this point, pretty much since this nation’s founding. From our own indigenous population, to Cuba and Central and South America, to Indochina to the Middle East, US administrations, both Republican and Democratic, have consistently impuned the principle of universality through unqualified dedication to American exceptionalism: What we do is right, what our enemies do is wrong, because we are good, and they are evil.
It’s a more nuanced history than that, obviously, but the trend holds up pretty well. At least the way I understand my American history (i.e., like a damn commie).
Matt Yglesias has more on McCain’s particular fondness for agression and empire:
I’m not sure the point can be made forcefully enough that John McCain is, among practical politicians, perhaps the single most committed advocate of an imperial vision of American foreign policy out there. This case can (and will!) be made at great length, but one quick way of getting at the point is through Teddy Roosevelt.
