Neither Paul nor Santorum won last night (though Paul may come out ahead in the delegate count before it is all over), but they make for a much more interesting story than the dreadful winner, so my new column for The Week is a comparison of their views with an emphasis on their foreign policy disagreements:

Indeed, Santorum’s politics are nearly the essence of Bushism. Paul represents the full-throated rejection of the same. If Paul is well-known for his strong anti-war views and sharp criticisms of U.S. interference abroad, Santorum has been no less outspoken in favor of ever more intrusive and interventionist policies. While Paul has been the lone voice warning against a rush to war against Iran, Santorum demands a more combative Iran policy. Santorum’s campaign rhetoric reads as if it were a caricature of neoconservatism. He believes that the U.S. is at war with “Islamic fascism,” which he sees a global threat on par with 20th century totalitarianism. He insists that we must promote democracy, but we must never allow democratic elections to empower Islamists. Oh, and terrorists hate us because we are free. U.S. policies have nothing to do with it.
