Miller's support for liberal forms of nationalism has been criticised by theorists such as Iris Marion Young, who stresses the need to develop forms of solidarity that extend beyond the state. It can be argued that Miller's assertion that we have greater ethical obligations to our co-nationals than to nationals of other states relies on an assumption that all states are equally well placed to provide for their citizens' needs, and defend their rights. Critics point out that this does not correspond to empirical reality. Young gives the example of natural resources, which are unequally distributed between states. She argues that their placement is morally arbitrary.
