That, my esteemed colleague, is the most naive and illogical statement I've ever 'heard' you make. Terrorists don't fabricate modern weapons like Stinger missiles from rocks and weeds they find laying around just outside their caves. Organized terrorists and their clandestine supporters purchase them from the black market and from covert weapons merchants just like everyone else. Of course, the ultimate in the creative application of technology at hand was the use of four commercial aircraft on 9/11/2001. To assume that terrorists sans portfolio cannot acquire and use a nuclear device is unwise at the least, and suicidal in the ultimate worst-case scenario.
