Contributor(s): Professor Arne Westad | When the Cold War ended, the threat of an all-out war between the superpowers ended with it. Nuclear war apparently went away. But while the political games changed, the nuclear arsenal that had done so much to keep the Cold War from ever turning hot remained very much in place. In this film, renowned historian of the Cold War Professor Arne Westad explains that not only have hopes for a dismantling of the weapons stockpile failed to be realised, but that the period since the end of the Cold War has seen proliferation occur at such a pace that ours is now referred to as "The Second Nuclear Age." Professor Westad also talks of his prevailing hope for a world free of nuclear weapons.
