This article by Lt. Col. Paul Yinling in the Armed Forces Journal, "A Failure in Generalship," amplifies the sentiment of my question in a diary last week, titled "Has American Military Leadership Lost Its Bearings?", which I thought had some interesting poll results.
Excerpts below the fold:
America's generals have repeated the mistakes of Vietnam in Iraq. First, throughout the 1990s our generals failed to envision the conditions of future combat and prepare their forces accordingly. Second, America's generals failed to estimate correctly both the means and the ways necessary to achieve the aims of policy prior to beginning the war in Iraq. Finally, America's generals did not provide Congress and the public with an accurate assessment of the conflict in Iraq.
Having spent a decade preparing to fight the wrong war, America's generals then miscalculated both the means and ways necessary to succeed in Iraq. The most fundamental military miscalculation in Iraq has been the failure to commit sufficient forces to provide security to Iraq's population. [snip]
These leaders would later express their concerns in tell-all books such as "Fiasco" and "Cobra II." However, when the U.S. went to war in Iraq with less than half the strength required to win, these leaders did not make their objections public.
After failing to visualize the conditions of combat in Iraq, America's generals failed to adapt to the demands of counterinsurgency. Counterinsurgency theory prescribes providing continuous security to the population. However, for most of the war American forces in Iraq have been concentrated on large forward-operating bases, isolated from the Iraqi people and focused on capturing or killing insurgents. Counterinsurgency theory requires strengthening the capability of host-nation institutions to provide security and other essential services to the population. America's generals treated efforts to create transition teams to develop local security forces and provincial reconstruction teams to improve essential services as afterthoughts, never providing the quantity or quality of personnel necessary for success.
After going into Iraq with too few troops and no coherent plan for postwar stabilization, America's general officer corps did not accurately portray the intensity of the insurgency to the American public. The Iraq Study Group concluded that "there is significant underreporting of the violence in Iraq." The ISG noted that "on one day in July 2006 there were 93 attacks or significant acts of violence reported. Yet a careful review of the reports for that single day brought to light 1,100 acts of violence. Good policy is difficult to make when information is systematically collected in a way that minimizes its discrepancy with policy goals."
