Washington - A new study of the doomsday cult linked to the Tokyo subway nerve gas attack says the case shows that given enough time and determination, terror groups can find ways to make weapons of mass destruction.
The report by ex-Navy Secretary Richard Danzig and other experts describes the cult's often bumbling efforts to make biological and chemical weapons, finally resulting in its deadly 1995 attack in the Tokyo subway.
Experts debate how difficult it would be for terror groups to make WMD.
The report released Thursday is based on interviews with senior cult members imprisoned in Japan. The 1995 attack killed 13 and injured 6,000.
The authors said that based on the cult's experience chemical weapons are probably easier to make than biological and nuclear weapons.
