Among the most important public health advances of the past century has been the development of potent vaccines against dangerous and life-threatening illnesses. Polio, tuberculosis, and measles quickly come to mind. Through a process of inoculation, a small dose of the pathogen is intentionally administered to the patient which induces immunity against the full-blown disease.

In a similar way, social scientists have demonstrated that attitude inoculation can be used to prevent the transmission of hazardous beliefs and behaviors from one person to another. For example, research reveals that adolescents can more effectively resist pressure from cigarette-smoking peers if they are given role-playing opportunities in which they rehearse their responses to students pressuring them to smoke.

But today we are in urgent need of an inoculation campaign against an entirely different threat to our nation's health--namely, the Bush administration's exploitation of its "global war on terror" to eviscerate the rule of law and our constitutional checks and balances; to prolong the disastrous occupation of Iraq; and to lay the groundwork for military strikes against Iran. Ever since the tragic events of 9/11 six years ago, the White House has promoted this agenda by working non-stop to spread a simple yet infectious idea: All actions taken by this president and his representatives are necessary to protect the United States from future catastrophic terrorist attacks.
