Abstract
Human rights have been the principal ethical ingredients of ‘ethical foreign policy’. Some human rights promulgated in UN and other Declarations are more aspirational than achievable; others are of variable importance. So we need to look behind the Declarations to see which human rights claims should be taken most seriously. I shall argue that we take rights seriously only if we take the counterpart obligations seriously, and can take obligations seriously only if we connect them to the capabilities of the agents and agencies who will have to discharge them. A realistic view of those agents and agencies cannot be based on the assumption that the relevant agents are all of them states, since this line of thought collapses where states are weak or failing. A realistic account of agency, or of obligations, a fortiori of rights has to take certain types of non-state actors and their obligations seriously.
