The identification of Western Civilization with Western Christianity (Catholic-Protestant) was not Huntington's original idea, it was rather the traditional Western opinion and subdivision before the Cold War era. Critics (for example articles in "Le Monde Diplomatique") call "The Clash of Civilizations and the Remaking of World Order" the theoretical legitimization of American-caused Western aggression against China and the world's Islamic and Orthodox cultures. Other critics argue that Huntington's taxonomy is simplistic and arbitrary, and does not take account of the internal dynamics and partisan tensions within civilizations. Furthermore, critics argue that Huntington neglects ideological mobilization by elites and unfulfilled socioeconomic needs of the population as the real causal factors driving conflict, that he ignores conflicts that do not fit well with the civilizational borders identified by him, and they charge that his new paradigm is nothing but realist thinking in which "states" became replaced by "civilizations". Huntington's influence upon U.S. policy has been likened to that of historian Arnold Toynbee's controversial religious theories about Asian leaders during the early twentieth century. The "New York Times" obituary on Huntington states that his "emphasis on ancient religious empires, as opposed to states or ethnicities, [as sources of global conflict] gained ... more cachet after the Sept. 11 attacks."
