Thomas Nagel's conservative position of the political conception for world politics and his insightful ‘Minimum Humanitarian Morality’ (MHM) view on global justice are laudable. He admits that the path from anarchy to justice must go through injustice. But Nagel does not clearly identify the conditions under which we put up with global injustice. This paper reviews the conception of MHM through the lens of the institutional political economy. In my view, to recognize the degree of structural failure (weakness in governance) as well as the degree of transition failure (elite bargain or personalization of power being interlocked) in each state can give us a hint on how to conceptualize and apply Nagel's MHM. We also argue that the scope and degree of humanitarian aid may vary in accordance with the options to global justice open to each state.
