WASHINGTON -- The terror of Sept. 11 is a key fissure in American lives. At Georgetown's McDonough School of Business, we investigated the repercussions of the terror on international marketing policy and corporate practices. We found a new era of common sense characterized by five key dimensions.

The first is a common sense of vulnerability. What happened in New York and Washington, D.C., can occur in any location around the globe.

There is a common sense of outrage -- no moral ambivalence here. These attacks touch individuals like a cold wind that makes sweat-beaded skin shiver.
