In his DNC speech, John F. Kerry said:

The United States of America never goes to war because we want to; we only go to war because we have to. That is the standard of our nation.

In today’s Washington Post, Robert Kagan points out that this statement is utter nonsense, and takes a hard look at The Kerry Doctrine. (Hat tip: gumble.)

Would it really be surprising if John Kerry, whose life and thought were so powerfully shaped by his Vietnam experience, now returned to the view of American foreign policy which that experience led him to three decades ago? There seems to be a conspiracy on both sides in this campaign not to take Kerry seriously as a man of ideas and conviction. But the fact that he has waffled so visibly on Iraq may be the best proof of his commitment to the beliefs about American foreign policy he came to hold in the 1970s.

Maybe Kerry’s real act of cynicism was his vote for the Iraq war in the fall of 2002. With that vote, he ignored everything he believed he had learned from his Vietnam experience. In retrospect, he may feel that he sold his soul to make himself electable. In the months since the war, Kerry has had to pretend he did the right thing, not only because a politician dare not admit error but because his political advisers believe that in a post-Sept. 11 world most of the electorate does not want an “antiwar” president. Throughout the long months of the campaign, Kerry disciplined himself to sound like a hawk. But in his heart, based on all he learned during the formative years of his life, Kerry is not a hawk. At the Democratic National Convention, John Edwards followed the script. Kerry followed his heart.

The ironies abound. Three decades ago, Kerry came out in opposition to the war he had fought in Vietnam. Today, Kerry extols that service so that he may safely, patriotically distance himself from the war in Iraq that he had supported.

If Kerry has revealed himself in an unusual moment of honesty, it’s time everyone took an equally honest look at where he would lead the country if elected. Kerry’s “doctrine of necessity,” if seriously intended, would entail a pacifism and an isolationism more thorough than any attempted by a U.S. government since the 1930s. It would rule out all wars fought for humanitarian ends, all interventions to prevent genocide, to defend democracy or even, as in the case of the Persian Gulf War, to uphold international law against aggression. For those are all wars of choice.
