When my son was killed in Iraq earlier this month at age 27, I found myself pondering my responsibility for his death. Among the hundreds of messages that my wife and I have received, two bore directly on this question. Both held me personally culpable, insisting that my public opposition to the war had provided aid and comfort to the enemy. Each said that my son's death came as a direct result of my antiwar writings. This may seem a vile accusation to lay against a grieving father. But in fact, it has become a staple of American political discourse, repeated endlessly by those keen to allow President Bush a free hand in waging his war. What exactly is a father's duty when his son is sent into harm's way? Among the many ways to answer that question, mine was this one: As my son was doing his utmost to be a good soldier, I strove to be a good citizen. As a citizen, I have tried since Sept. 11, 2001, to promote a critical understanding of U.S. foreign policy. I genuinely believed that if the people spoke, our leaders in Washington would listen and respond. This, I can now see, was an illusion. The people have spoken, and nothing of substance has changed. The November 2006 midterm elections signified an unambiguous repudiation of the policies that landed us in our present predicament. But half a year later, the war continues, with no end in sight. Indeed, by sending more troops to Iraq (and by extending the tours of those, like my son, who were already there), Bush has signaled his complete disregard for what was once quaintly referred to as the will of the people." To be fair, responsibility for the war's continuation now rests no less with the Democrats who control Congress than with the president and his party.
