The document discusses nuclear proliferation and whether the US should try to slow hostile nations' acquisition of nuclear weapons. It notes the risks of proliferation but also the risks of non-proliferation efforts. Experts cite treaties like the NPT to promote non-proliferation but also acknowledge some countries remain outside these agreements. Original survey research in the document found most respondents saw the risks of proliferation as outweighing the benefits and thought hostile nations could become angry over non-proliferation efforts, yet some still felt the US should try to slow nuclear programs in these nations.
