John McCain has been said to have neoconservative inclinations; to critics, this suggests a commitment to the unilateral deployment of military force to bring about a democratic transformation in once-hostile countries. The question of whether he’s a neocon, however, is not entirely relevant; McCain has advisers from both the neocon and realist camps, and he’s too inconsistent to be easily labeled. In one area, though, he has been more or less constant: his belief in the power of war to solve otherwise insoluble problems. This ideology of action has not been undermined by his horrific experience as a tortured POW during the Vietnam War, or by the Bush administration’s disastrous execution of the Iraq War. All this is not to suggest that McCain is heedlessly bellicose or reflexively willing to send U.S. soldiers into danger; he is the father of a marine and a Naval Academy midshipman, James McCain and John S. McCain IV, whose service he rarely mentions. And he opposed, presciently, keeping the Marines in Beirut in 1983, just before their barracks were bombed. But his willingness to speak frankly about the utility of military intervention sets him apart from his opponent. Senator Obama, though certainly no pacifist, envisions a world of cooperation and diplomacy; McCain sees a world of organic conflict and zero-sum competition.
