Some 20 American citizens, some with middle class aspirations, have joined a terrorist group in their native Somalia. Two have been shot dead, one a suicide bomber, and at least 15 others have disappeared. Two more have been indicted in federal court in Minnesota, charged with providing support for terrorists and conspiracy to “kill, kidnap, maim or injure” people in foreign countries. Federal authorities say they're just part of a major investigation which became public on Monday of this week. Will Somalia be a breeding ground for international terror? Is al Qaeda exploiting a failed state? Will other naturalized Americans be vulnerable to militant Islam?
