Where it is not augmented by depraved Bin Ladenist imports, the leadership and structure of the Iraqi "insurgency" is formed from the elements of an already fallen regime, extensively discredited and detested in its own country and universally condemned. This could not be said of Ho Chin Minh or of the leaders and cadres of the National Liberation Front.
The option of accepting a unified and Communist Vietnam, which would have evolved toward some form of market liberalism even faster than China has since done, always existed. It was not until President Kennedy decided to make a stand there, in revenge for the reverses he had suffered in Cuba and Berlin, that quagmire became inevitable. The option of leaving Iraq to whatever successor regime might arise or be imposed does not look half so appetizing. One cannot quite see a round-table negotiation in Paris with Bin Laden or Zarqawi or Moqtada Sadr, nor a gradually negotiated hand-over to such people after a decent interval.
In Vietnam, the most appalling excesses were committed by U.S. forces. Not all of these can be blamed on the conduct of bored, resentful, frightened conscripts. The worst atrocities—free-fire zones, carpet-bombing, forced relocation, and chemical defoliation—were committed as a direct consequence of orders from above. In Iraq, the crimes of mass killing, aerial bombardment, ethnic deportation, and scorched earth had already been committed by the ruling Baath Party, everywhere from northern Kurdistan to the drained and burned-out wetlands of the southern marshes. Coalition forces in Iraq have done what they can to repair some of this state-sponsored vandalism.
In Vietnam, the United States relied too much on a pre-existing military caste that often changed the local administration by means of a few tanks around the presidential palace. In the instance of Iraq, the provisional government was criticized, perhaps more than for any other decision, for disbanding the armed forces of the ancien regime, and for declining to use a proxy army as the United States had previously done in Indonesia, Chile, El Salvador, and Greece. Unlike the South Vietnamese, the Iraqi forces are being recruited from scratch.
In Vietnam, the policy of the United States was—especially during the Kennedy years—a sectarian one that favored the Roman Catholic minority. In Iraq, it is obvious even to the coldest eye that the administration is if anything too anxious to compose religious differences without any reference to confessional bias.
I suppose it's obvious that I was not a supporter of the Vietnam War. Indeed, the principles of the antiwar movement of that epoch still mean a good deal to me. That's why I retch every time I hear these principles recycled, by narrow minds or in a shallow manner, in order to pass off third-rate excuses for Baathism or jihadism. But one must also be capable of being offended objectively. The Vietnam/Iraq babble is, from any point of view, a busted flush. It's no good. It's a stiff. It's passed on. It has ceased to be. It's joined the choir invisible. It's turned up its toes. It's gone. It's an ex-analogy.
