Collounsbury has an excellent deconstruction of the Peter Galbraith review of the American Occupation of Iraq
as it was horribly bungled in most every respect by the CPA. The military often performed superbly, particularly in liberating Iraq from Saddam's megalomaniac despotism but where it needed good civilian direction, advice and support, it received none. Some of what I have received via email from personal reports on the ground in Iraq struck by someone involved on the military operation side of things struck me as both ominous and bizarre at the time. Iraq would never have been easy but done correctly, competently, more ruthlessly with sufficient resources it would not be a country today about to limp off a cliff.
By mishandling Iraq the Bush administration has jeopardized their entire strategy of dealing with the interrelated problems of terror, rogue state behavior, weapons proliferation, radical Islamism and boosted those who want to return to a policy of studiously ignoring the whole mess and papering over strategic problems until the next 9/11 arrives.
