Charles Krauthammer examines why the Left, against going into Iraq, is now so keen on going into Liberia. Here is the crux, and it’s not pretty: "The only conclusion one can draw is that for liberal Democrats, America’s strategic interests are not just an irrelevance, but a deterrent to intervention. This is a perversity born of moral vanity. For liberals, foreign policy is social work. National interest - i.e., national selfishness - is a taint. The only justified interventions, therefore, are those which are morally pristine, namely, those which are uncorrupted by any suggestion of national interest. Hence the central axiom of left-liberal foreign policy: The use of American force is always wrong, unless deployed in a region of no strategic significance to the United States."
