true libertarians are completely anti-war, anti-empire, they despise Palin and her ilk
this tactic of simply lumping in neo-con war mongers into the libertarian camp is very problematic, as is the number of right-wing statists who self-describe as libertarian
I highly doubt this talk show host has ever read a single serious treatise from a foundational libertarian philosopher. To be honest, even a first-year student here at Stockholms Universitet Political Science Department would systematically refute the entire premiss of his demagogic argument, as it contains numerous logical fallacies.

The result -- and a natural one -- has been that we have had governments, State and national, devoted to nearly every grade and species of crime that governments have ever practised upon their victims; and these crimes have culminated in a war that has cost a million of lives; a war carried on, upon one side, for chattel slavery, and on the other for political slavery; upon neither for liberty, justice, or truth. And these crimes have been committed, and this war waged, by men, and the descendants of men, who, less than a hundred years ago, said that all men were equal, and could owe neither service to individuals, nor allegiance to governments, except with their own consent."
