Well, first of all, the KR were not strictly "national terrorists" since they crossed the Vietnamese border and killed hundreds of Vietnamese in their mad ethno-quest for Greater Kampuchea. And the Vietnamese quite rightly responded with full force and drove Pol Pot's gang into the Thai jungle. That was a legitimate use of self-defense, despite what the West and its Chinese friends saw as "Prussianism."
As for the Bush gang, yes, they are fucked up in so many ways. But I don't recall anyone saying that the government should protect its citizens from foreign attack *except* in the case of an "asinine oligarchy." And don't underestimate al-Qaeda; they are not a bunch of "Al Capones" but a very serious, violent threat to what they see as an infidel existence. They are not neighborhood gangsters looking for black market share, but are international theocratic fanatics who wish to impose a Wahabbi state on believers and non-believers alike. Look at what they did to Afghanistan, and tell me how 1920s Chicago compares to that.
