There are terrorist groups in America.
They aren't Al Qaeda.
They claim that ridding the country of foreigners "by any means necessary" is their mission. They've planted bombs. These bombs have gone off. Some have been arrested, after extensive manhunts by our FBI. Others are still fugitives. Some have lived in caves. They're part of coordinated organizations and networks. They're part of international networks. And yet nobody in this country knows their names. They don't spend the week on the front pages of our newspapers like Faisal Shahzad.
So why does America ignore these bombers? I think it's clear. It's because a large segment of our culture sympathizes with their mission.
