WASHINGTON (AFP) From blue-eyed Jihad Janes to naturalized US citizens born in Muslim countries, homegrown terrorists have become a serious threat in the United States since the September 11, 2001 attacks, a report issued Friday said. The report by the Bipartisan Policy Centers National Security Preparedness Group says US domestic security agencies are ill-prepared to tackle the emerging threat. At least 43 American citizens or residents linked to Muslim militant groups or who embraced radical Islam were charged or convicted last year of terrorism crimes in the United States and abroad, the report said. A few years ago, the number was zero, said Bruce Hoffmann, who authored the report together with Peter Bergen, an expert on Al-Qaeda. The new face of terrorism in the United States is not the same as the young Middle Eastern men who slammed passenger jets into the World Trade Center in New York and the Pentagon in Washington nine years ago, the report said. Potential terrorists now hail instead from a variety of ethnic, educational and economic backgrounds. Terror attacks have been planned or carried out in the past year in the United States by affluent suburban Americans and the progeny of hard-working immigrants... persons of color and Caucasians... women along with men, the report said. American residents and citizens who have been drawn to radical Islam and terrorism have been good students and well-educated individuals, high school dropouts and jailbirds. They are persons born in the US or variously in Afghanistan, Egypt, Pakistan, and Somalia. They are teenage boys pumped up with testosterone and middle-aged divorcees, the report added, in one of many references to Jihad Jane Colleen LaRose, a divorcee from a Philadelphia suburb who allegedly wanted to use her blond, blue-eyed looks to blend in in Sweden and kill a cartoonist who had offended radical Muslims.What we see is an adversary that is drawn from all sectors of society and all walks of life, said Hoffman. Commercial airlines remain a prime target for terrorists, because of the fear even a failed attack on an airline sows worldwide, and the impact on the global economy, the report said. But catastrophic-scale attacks such as those nine years ago were unlikely. Terrorist groups have made a strategic shift away from spectacular attacks towards smaller attacks, such as the shootings at Fort Hood military base in Texas, where a Palestinian-American army officer last year shot dead 13 people; or car bombs, such as the foiled attack in New Yorks Times Square in May by a Pakistani-American, said the report. Smaller scale attacks carried out by homegrown groups are more difficult to intercept and detect, said Stephen Flynn, president of the Center for National Policy at the launch of the report. They require less centralized planning and coordination and are seen by terror groups as giving more bang for the buck by generating huge amounts of media attention even if they fail, like the Christmas Day 2009 attempt to blow up a commercial airline. But although the faces of the terrorists, the language they speak and the way they attack the United States may have changed, one thing remained constant, said the experts. Theyre still after us and still want to do us harm, said Flynn. And one day, one of these small attacks will succeed, he said. Domestic security agencies have long felt that homegrown terrorism couldnt happen in the melting pot of the United States, and that belief has left the country ill-prepared to tackle the new threat, said Hoffman. There is no single government agency responsible for identifying radicalization and interdicting recruitment, and its not clear which agency among the vast array in law enforcement and intelligence should have lead responsibility, he said. Terrorists may have found our Achilles heel we have no strategy for dealing with this emerging threat.
