Is the Bush strategy of Pre-emptive Attack Unjust?

The US Army War College journal published an article suggesting that Operation Iraqi freedom did not meet meet the Just War test.

The 2002 National Security Strategy, then, is used to justify selective killing of some to achieve a greater good of liberty for many others, driven by an idealistic approach for universal human freedom. This is a strategic move oriented toward future vision and away from the recent, realist historical politics of a balance of power or a balance of terror. In the ethical framework of increased good for the most people and balancing ethical ends and means, the Bush doctrine advances democracy at the tip of a spear. This application of military force presents a moral dilemma.

The case of Operation Iraqi Freedom is a catalyst for further thinking about this new ethic regarding the use of force, particularly the leaner, rapid, decisive, lethal new force of the US military. The pivotal issue about retaining “imminent threat” but redefining its criteria for preemptive self-defense is driven by the threat of terrorists with the means and motives to employ weapons of mass destruction. Until further moral thinking provides a more substantial ethical framework for decisionmaking, however, it seems proper to withdraw references to preemption as a doctrinal element of the National Security Strategy. Further, even should nations proceed toward a new ethic for launching war preemptively or preventively, consideration of second-order effects is important. Even accepting the benefit of preventing Iraq from obtaining nuclear weapons, will other nations pursuing nuclear weapons move more quickly and covertly, believing the United States would attack during their pursuit of WMD (such as Iraq) but not nations possessing them (such as North Korea)?.

As I follow the news, it becomes clear that the Army brass does not like the Pentagon neocons. They overestimated the WMD threat and failed to plan for occupation.

Over at IntelDump, Phillip Carter, writing about Bush, suggests
Supreme Command : Soldiers, Statesmen, and Leadership in Wartime" by Eliot Cohen — that he strives to emulate great wartime leaders like Lincoln and FDR. If that's true, then maybe he needs to cruise across the Potomac and fire a few people in the war department, just as Lincoln and FDR did..
I agree.
