Abstract
The language of Global Zero (GZ) initiated from the US and got currency particularly after the Obama’s Prague speech. The GZ phenomenon is simple to pronounce but gets difficult and complex when it comes to changing contours of the international politics. Although the GZ phenomenon reminds both the nuclear and non-nuclear weapons states of the commitments that they would work for a complete disarmament, which in turn, becomes one of the important ingredients of the non-proliferation regime, both the major and minor nuclear weapons states have yet to work on these commitments. This article is to find out the relevancy of GZ in today’s changed strategic environment amongst all nuclear weapons states irrespective of the region, these states belong to. It is to find out the complexities associated with the GZ and what they mean for the world free from nuclear weapons. While analyzing the difficulties the GZ confronts both at the regional and international level, this article aims at finding out whether or not the language of GZ remains any longer relevant in the nuclear politics and ultimately how this would affect the non-proliferation regime.
