In his first major book, conservative columnist Steyn takes on the anti-Americanism that fuels both Old Europe and radical Islam. America, Steyn argues, will have to stand alone. The future, Steyn shows, belongs to the fecund and the confident. The Islamists are both, while the West--wedded to a multiculturalism that undercuts its own confidence, a welfare state that nudges it toward sloth and self-indulgence, and a childlessness that consigns it to oblivion--is looking ever more like the ruins of a civilization.
