Europe Poses Terrorism Threat, Chertoff Says -- by Rob Gifford

Homeland Security Secretary Michael Chertoff said Wednesday that one of the biggest threats to U.S. security may now come from Europe. --- The visa-waver program, which applies to 27 countries, presents the U.S. and European governments with a problem. Any measures targeting those of certain ethnic or religious background would be controversial, and Chertoff reassured that that was not the plan.
