One can say that the historical task and political purpose of neoconservatism would seem to be this: to convert the Republican party, and American conservatism in general, against their respective wills, into a new kind of conservative politics suitable to governing a modern democracy.
...
The steady decline in our democratic culture, sinking to new levels of vulgarity, does unite neocons with traditional conservatives--though not with those libertarian conservatives who are conservative in economics but unmindful of the culture. The upshot is a quite unexpected alliance between neocons, who include a fair proportion of secular intellectuals, and religious traditionalists. They are united on issues concerning the quality of education, the relations of church and state, the regulation of pornography, and the like, all of which they regard as proper candidates for the government's attention. And since the Republican party now has a substantial base among the religious, this gives neocons a certain influence and even power. Because religious conservatism is so feeble in Europe, the neoconservative potential there is correspondingly weak.
