**Analysis**
The text appears to be discussing the feasibility and implications of a comprehensive nuclear test ban treaty. It provides statistics on the types of nuclear tests conducted, as well as the arguments for and against such a treaty. The text seems to be focused on the political and scientific aspects of nuclear weapons, rather than their economic or environmental impact. Therefore, it is likely that the category is related to international relations or science and technology.
