AP-The US can expect a terrorist attack using nuclear or more likely biological weapons before 2013, reports a bipartisan commission in a study being briefed tomorrow to Vice President-elect Joe Biden. It suggests the Obama administration bolster efforts to counter and prepare for germ warfare by terrorists. "Our margin of safety is shrinking, not growing," states the report, obtained by the AP. It is scheduled to be publicly released Wednesday. The commission is also encouraging the new White House to appoint one official to coordinate US intelligence and foreign policy on combating the spread of nuclear and biological weapons. "The United States should be less concerned that terrorists will become biologists and far more concerned that biologists will become terrorists," the report states. SOURCE Associated Press
