The nation’s top general for domestic security says he has seen little evidence to suggest an imminent terrorism threat inside the United States by members of Al Qaeda’s network, and warns against using “McCarthyism” in combating terror.

“I am not aware of a significant threat to this nation” from so-called sleeper cells, said the officer, Gen. Ralph E. Eberhart.

General Eberhart, who as head of the military’s newly created Northern Command oversees the Pentagon’s contribution to domestic counterterrorism efforts, expressed concern that undetected terrorist cells could be operating in the United States and plotting new attacks. NY Times
