But the article does make a good point, in that there are essentially two very different types of isolationsists; [1] those who view "Americanization" of the world as doing more bad than good, and the far more common type, which, as I mentioned, [2] basically don't give a damn about what goes on outside of our borders.
Likewise, interventionists can be [3] both those who view the United States as a force for good in the world, or[4] those who want to make the rest of the world more like us so as to better serve our interests.
Or as the highly-flawed yet interesting Christian Science Monitor article of 2004 put it...[1] = Liberal; [2] = Isolationist; [3] = Neoconservative; [4] = Realist.
Ah, Rome. The vilest motherfucker in earth history. Rome well deserved all the hate it got and something extra, you know that? Believe you me, you don't want to take Rome as your role model, because if you do, that'd really be the end to whatever civil liberties you got left.
Well, to be technical, the Roman
Republic was pretty damn good, especially by the standards of the era - you had places rebelling in order
to become Roman citizens. Once the transition to the Roman
Empire took place, things headed south in a hurry.
My source, BTW, was my always-entertaining libertarian Ancient History professor back in my undergraduate days, whose specialty was Greece and Rome.
