The United States now spends almost as much on defense in real dollars as it ever has before -- even though it has no plausible rationale for using most of its impressive military forces. Why? Because without political incentives for restraint, policymakers have lost the ability to think clearly about defense policy. Washington's new mantra should be "Half a trillion dollars is more than enough."

The failure to prevent the September 11, 2001, attacks or find Iraqi WMD have put intelligence at the center of this year's presidential campaign. The key to better performance, however, lies not in major reforms but in the character and sense of responsible officials.

President Bush's case for war on Iraq overlooks a very real danger: if pushed to the wall, Saddam Hussein may resort to using weapons of mass destruction against the United States. Such a strike may not be likely, or may not succeed, but attacking Saddam is the best way to guarantee that it will happen. And Washington has done far too little to prepare for it.

The risk of a catastrophic exchange of nuclear missiles has receded. Yet the chances of some use of weapons of mass destruction have risen. Chemical weapons are a lesser threat, but more likely. A vial of anthrax dispersed over Washington could kill as many as three million. Traditional deterrence will not stop a disgruntled group with no identifiable address from striking out at America. The United States must pull back from excessive foreign involvements and begin a program of civil defense to reduce casualties in the event the unthinkable happens.

The United Nations and the United States continue to intervene in wars without forthrightly taking sides. Impartiality may sound sensible enough, but it has hamstrung would-be peacekeepers and worsened conflicts in Bosnia, Somalia, and, to some degree, Haiti. War is about who rules. If military intervention occurs, outsiders should ensure someone is in charge at the end of the day. Interventions that avoid the root issue and aim to be evenhanded become compromises that kill. They prevent the very peace they seek to create.
