Nuclear arms, climate change, and the structural consequences of a global capitalist economy are currently the three predominant issues that demand global collective action on the part of national governments. Since these issues all concern “hard” issues of security (from nuclear to food security), strong political responses are in principle necessary. And if efficacy of remedy is only possible through limited cession of sovereignty, the concept of “political duty” must be appropriately rethought in order to frame this requirement normatively. States have accordingly the political duty to pool and/or yield national sovereignty so that effective action on these issues is possible. They have the duty, that is, to pool and/or yield external sovereignty (sovereign independence) in order to maintain internal sovereignty (the maintenance of primary domestic state functions)
