You'll need an ironclad definition of what Western values are and what a western society is and then you'll have to first go after everything that is homegrown that is also against those values. Ironically you'll find a ton of domestic parties that would like nothing better than to destroy their own select set of those.

And then there is the little problem that Western values and society are still so young that they haven't fully formed yet. And to an American it means something completely different than to a Canadian, a Briton, a West European and an Eastern European. And then there is the Nordics, the Baltics and so on. It will have to be a real work of art to make that workable.
