Neoconservatism is an almost purely foreign-policy ideology, at least as I understand it. The use of American military might to remake certain parts of the world (specifically the middle east, although I doubt they'd have stopped there) into (radically) free-market pro-American democracies. The markets so created were supposed to be dominated by American corporations, with the governments of the countries we "liberated" having little or no say in the distribution of their nation's resources. "To the victors go the spoils." I guess they figured the people of those countries would be OK with that, or at least be unable to do anything about it. Iraq was their big test case, and if you were listening to their confident predictions before the war, you'll remember what they thought was going to happen. Oops.
Neoconservatism hasn't really had much of a domestic agenda, except as it relates to securing the power they needed to put their plans into place. Many of the political actors from the movement have had domestic policy ideas, but that's not quite the same thing. They are more than simply neo-cons. They're neo-cons, plus whatever else they are politically. The "pure" neo-conservatives, like Fukuyama, Wolfowitz and Perle, never cared much for domestic policy, and certainly never contributed anything in the way of ideas in that realm.
It's a nationalistic, might-makes-right, idealistic ideology, dreamed up by some right-wing academics and a bunch of parasites who've gotten rich by moving from government service to corporate boardrooms and back again. Tellingly, none of these folks has ever put on a uniform. That they so completely miscalculated what would happen when their pet thoeries were put into the real world is typical of those whose "knowledge" is purely theoretical, based only on a study of things other people have done.
What is Neoconservatism? A total, end-to-end, unremitting failure. Which we will be paying for, in blood and treasure, for at least a generation. Will it be the end of us? No, I don't think it will. But undoing the damage it has caused will take a lot longer than it took to do the damage in the first place. Ain't entropy great?
