The call for complete nuclear disarmament is as old as the nuclear era itself. But as the Cold War warmed up, neither a string of UN resolutions nor large scale anti-nuclear protests could put brakes on the nuclear arms race. By the mid-Eighties, the US and USSR were holding about 60,000 weapons between them. The goal was briefly revived a decade ago by President Obama’s passionate call for a nuke-free world. Other world leaders including President Medvedev welcomed the call and a host of scholars had started working on road maps to reach “Nuclear Zero”. But, harsh realities are asserting themselves again. Not only are some countries continuing to produce more weapons, but the US -Russia relationship has turned for the worse. Treaties designed to reduce nuclear dangers are unravelling. Nuclear weapons seem to be here to stay, at least for the foreseeable future.
