For many Americans the "Shock and Awe" honeymoon phase has long been over in Iraq. In fact, the latest statistics support the gradual disillusionment with the efforts in Iraq. It is interesting to track the rise and fall of the American public's response to the war based on the events as they happen.
In December 2001 70% of Americans supported the idea of going into Iraq and ousting Saddam Hussein. And support for the war peaked at 76% in 2003 as Saddam Hussein's regime fell.
By May of 2007 the approval rating for the Iraq invasion had dropped to just 35%. And on this 5-year anniversary of the invasion the approval rating for the war is just under 40%.
The plummeting of the approval for the war is hardly newsworthy, but I have often wondered, "Why the considerable shift in support?" What has changed since we first invaded in 2003?
There are a number of reasons opponents of the war want the U.S. out of Iraq: 1.) The Bush administration lied to get us into Iraq (I've never fully bought into this argument, because it assumes that those in the Bush administration knew full well that there were no WMD's to be found, for example, but willingly perpetuated that lie in order to put our military men and women in harm's way because of some hubristic motivation. Faulty intelligence irresponsibly applied? Plausible. An outright lie? Difficult to realistically believe.)
2.) The cost of the war, both in money and lives, is a legitimate concern. However, the "no more blood for oil" rationale is somewhat hollow coming from anyone who drives a vehicle to work everyday, among other means of oil consumption. More importantly, this cost of the war raises the issue, "When does the cost of such an endeavor move from being worthwhile to being irresponsible?" Different people will certainly come down at different points on this issue. Regardless, however, are there still costly endeavors that are worth our sacrifice?
There are other reasons opponents give, but the point is this: What accounts for the significant swing in support for the war? Put another way, why did so many of us support the war at the beginning, when so many do not now? What changed?
Did our rationale for going to war change? The search for WMD's was part of it, but so was the intent to free the Iraqi people from the grip of a murderous dictator. To free people from oppression and violence is a noble endeavor. After all, there are growing cries for intervention in Darfur, just as there were during the 1994 Rwandan genocides.
If we were watching children get repeatedly beat up by the bully on the playground, we would hopefully intervene to protect the innocent. To translate that analogy on a global scale is certainly more difficult, but the question remains, at what point do we have an obligation to intervene on behalf of the oppressed in our world?
In Iraq, there will be ongoing differences of opinion about whether we should stay or go. As I've written before, some may wish we hadn't gone into Iraq, but the fact is, we're in Iraq, facing a dangerous enemy. So, what do we do now?
More importantly, has the enemy we faced then changed? In fact, I've often wondered what our liberal friends believe will happen if we pull out prematurely? What will the terrorists do once the American presence is gone?
James Joyner asserts some very interesting analysis from Outside the Beltway regarding the dilemma opponents of the war face.
The truth is, the vast majority of Americans want our soldiers out of harm's way, myself included. The point of difference comes regarding how/when this should happen.
As I have articulated at various points on this blog, it is only the madman who relishes violence. But at times violence is a tragic necessity in order confront the evil which exists in our world. Do we have the perseverance to ensure that the job we set out to do five years ago in Iraq will be done in the right way? I hope so (and I presume the Iraqi people hope so as well).
