Check the bibliography for sites with information related to the proliferation of nuclear weapons. I have provided the links in the entries. The American Institute provides a perspective on nuclear policy from the scientific community and loads of knowledge on nuclear science and engineering. The Council on Foreign Relations, an independent policy group, has a fantastically informative presentation. You also have a right to know about military nuclear operations so check the Department of Defense, CIA, and Homeland Security websites. Wikipedia provides a plethora of knowledge for your own reading sourced from trusted sources. Lastly, make sure that you are informed on the news; it is a civic duty to the world.
