Nuclear scientist Question:

Al Qaeda has repeated expressed its intent to launch nuclear attacks on American soil. Pakistan’s nuclear facilities have been attacked three times since 2007. South Africa’s Pelindaba nuclear site was breached by gunman in 2007. According to Warren Buffet, concerned over his major stake in the insurance industry, a nuclear terrorist strike is matter not if, but when: “We’re going to have something in the way of a major nuclear [terrorist] event in this country. It will happen. Whether it will happen in 10 years or 10 minutes, or 50 years … it’s virtually a certainty.” Do we want to give terrorist elements–or even a “lone wolf” — thousands of new sources of radioactive material and the ability to kill thousands of people with one successful attack?
