In recent years theorists, such as Yael Tamir and David Miller, have proposed a liberal form of nationalism thereby combining two seemingly incompatible traditions of thought. Perhaps the most controversial element of their theories is the claim that national communities should be accorded with a right to political self-determination. In the article it is explained, firstly, why membership in a nation is seen as important for the individual’s well-being and, secondly, why statehood is deemed necessary for the thriving of the nation. Subsequently, two problems of the liberal nationalists’ argument for political self-determination are discussed. It is argued, firstly, that national communities only need some form of regional autonomy to achieve their most important goals and, secondly, that non-national communities, e.g. religious groups, can base their demand for political sovereignity on the very same argument.
