The Petraeus Doctrine

Andrew Bacevich writes in The Atlantic Monthly:

A leading voice in the Conservative camp is Colonel Gian Gentile, a Berkeley graduate with a doctorate in history from Stanford, who currently teaches at West Point. Gentile has two tours in Iraq under his belt. During the second, just before the Petrae­us era, he commanded a battalion in Baghdad.
Writing in the journal World Affairs, Gentile dismisses as “a self-serving fiction” the notion that Abrams in 1968 put the United States on the road to victory in Vietnam; the war, he says, was unwinnable, given the “perseverance, cohesion, indigenous support, and sheer determination of the other side, coupled with the absence of any of those things on the American side.” Furthermore, according to Gentile, the post-Vietnam officer corps did not turn its back on that war in a fit of pique; it correctly assessed that the mechanized formations of the Warsaw Pact deserved greater attention than pajama-clad guerrillas in Southeast Asia.
Gentile also takes issue with the triumphal depiction of the Petrae­us era, attributing security improvements achieved during Petrae­us’s tenure less to new techniques than to a “cash-for-cooperation” policy that put “nearly 100,000 Sunnis, many of them former insurgents, … on the U.S. government payroll.” According to Gentile, in Iraq as in Vietnam, tactics alone cannot explain the overall course of events.
All of this forms a backdrop to Gentile’s core concern: that an infatuation with stability operations will lead the Army to reinvent itself as “a constabulary,” adept perhaps at nation-building but shorn of adequate capacity for conventional war-fighting.
