It mentions the development of a bipolar distribution of military force, the threat of nuclear weapons, and the need for international cooperation to address these issues. The text also touches on the concept of zones of peace and the principles of the United Nations Charter. Given the focus on international security and military forces, it seems likely that the text is related to the category of international relations.
