Das Ukraine-Dilemma, die Lehre vom gerechten Krieg und der Pazifismus

Abstract How much help are third countries morally allowed or obliged to provide for a state unjustly attacked by a state that might widen a local war into a nuclear world war? This question leads to the Ukraine dilemma. It faces states that deliberate their obligations to the Ukraine unjustly attacked by Russia that might use nuclear weapons. To clarify the question, I examine the two most important evaluations of wars, the just war doctrine ( D ) and pacifism ( P ). My theses are: (1) D is a moral theory, but P is not. P is a practical metaphysics, so they do not exclude one another. (2) Augustine shaped D and directed it against P , interpreting P and tendentially Christianity as moral theories, losing the distinction between practical metaphysics and morality, followed suit by the Enlightenment and current normative theory. (3) To solve the Ukraine dilemma, we must rely on an uninterpreted morality and prudence.
