Nuclear Proliferation

So everyone knows that Iran and North Korea have been working on nuclear power, and possibly nuclear weapons. But what I just learned today was that over 40 other nations are also on the brink of starting their own nuclear programs. Could you imagine a world where Namibia, South Africa, Argentina and Brazil had nuclear missiles. We were scared shitless during the Cold War when it was only us and Russia. The future where any third world nation or military dictatorship can have these weapons is a bleak one. Oh one positive note, Canada is one of the 40 nations, there's nothing to fear from Canada!
