What We Owe to Ukrainians: A Moral Perspective on Nuclear Coercion and Military Intervention.

Ukraine's war of self-defense against Russia is one of the clearest examples of a nation fighting a just war in recent history. Ukraine is clearly entitled to defend itself, and Russia is clearly obligated to cease hostilities, withdraw troops, and make repair. In light of this, some of the most salient moral questions related to Russia's war of aggression in Ukraine involve the international community; namely, what moral duties it has toward Ukraine, especially in light of Russia's extreme and pervasive human rights abuses. The first section of the essay argues that there is a pro tanto moral duty to intervene militarily in Ukraine to stop Russian human rights abuses and ensure that Ukraine achieves a military victory. This duty is grounded in duties of rescue, promissory obligations, and reliance obligations, as well as duties to nations' own citizens and to the international community. The second section of the essay argues that the most relevant consideration in determining whether there is an all-things-considered duty for the international community to intervene militarily in Ukraine is Russia's nuclear coercion and the associated risk of nuclear war. This section highlights the nuclear risks involved in compliance with Russian nuclear coercion, which I argue have been neglected in prominent discussions. The moral stakes involved in this determination are very high, and succumbing to Russian nuclear coercion in the face of massive human rights violations would set a dangerous precedent. Any course of action should be guided by a thorough analysis of all the risks involved, both nuclear and moral. [ABSTRACT FROM AUTHOR]
