Professor Chomsky, writing for TomDispatch, takes apart the common notion among mainstream liberals that GW Bush took America “off course,” noting a history of torture and barbarous expansion that dating back to 1630. Throughout, he touches on the widely-held understanding that America sees itself as unique in the world:

The reigning doctrine of the country is sometimes called “American exceptionalism.” It is nothing of the sort. It is probably close to a universal habit among imperial powers. France was hailing its “civilizing mission” in its colonies, while the French Minister of War called for “exterminating the indigenous population” of Algeria. Britain’s nobility was a “novelty in the world,” John Stuart Mill declared, while urging that this angelic power delay no longer in completing its liberation of India.

Similarly, there is no reason to doubt the sincerity of Japanese militarists in the 1930s, who were bringing an “earthly paradise” to China under benign Japanese tutelage, as they carried out the rape of Nanking and their “burn all, loot all, kill all” campaigns in rural North China. History is replete with similar glorious episodes.

As long as such “exceptionalist” theses remain firmly implanted, however, the occasional revelations of the “abuse of history” often backfire, serving only to efface terrible crimes. The My Lai massacre was a mere footnote to the vastly greater atrocities of the post-Tet pacification programs, ignored while indignation in this country was largely focused on this single crime.

Watergate was doubtless criminal, but the furor over it displaced incomparably worse crimes at home and abroad, including the FBI-organized assassination of black organizer Fred Hampton as part of the infamous COINTELPRO repression, or the bombing of Cambodia, to mention just two egregious examples. Torture is hideous enough; the invasion of Iraq was a far worse crime. Quite commonly, selective atrocities have this function.

Historical amnesia is a dangerous phenomenon, not only because it undermines moral and intellectual integrity, but also because it lays the groundwork for crimes that still lie ahead.
