What aspect does nuclear ethics directly relate to when discussing nuclear weapons?

Nuclear ethics fundamentally focuses on the moral implications surrounding the existence and use of nuclear weapons. This encompasses a wide range of ethical questions, including considerations of just war theory, civilian casualties, the long-term consequences of nuclear warfare, and the responsibilities of nations to prevent proliferation and ensure global security.

While technological advancements in weaponry and economic impacts are important subjects in the discourse surrounding nuclear weapons, they do not inherently encompass the ethical considerations that guide decision-making and policy related to these weapons. Additionally, while the environmental effects of nuclear weapons on wildlife represent significant concerns, they are part of a broader ethical discussion rather than the core focus of nuclear ethics itself. This makes the moral implications central to understanding the ethical framework within which nuclear weapons are debated and evaluated.
