We live in a state-centric world faced with global-scale problems that cannot be met by the actions of single states, no matter how powerful, if assessed from the perspective of military capabilities.

On the cautionary side, Universal Jurisdiction could be used to achieve some kind of ideologically motivated criminalisation of 'the other' that would discredit and derail a constructive effort to develop a credible meta-law that governs the behaviour of leaders of sovereign states.

There is no effort to acknowledge some equivalent accountability by associating "terrorism" with all violence that is deliberately aimed at civilians, either directly or as foreseeable effects of violent acts, whether the actor is a non-state individual or group or the state.

To achieve effectiveness and legitimacy it is time to scrap the right of veto given to permanent members of the UN, or at least severely restrict its use. It is also time to either abandon the idea of permanent membership or broaden it to reflect the rise of non-Western states to the status of global leaders (e.g. Brazil, India, Indonesia, Turkey, South Africa), and to downgrade European representation by either giving the European Union a single seat or rotating a European state among Germany, France, UK, and Italy.

The weaknesses and biases of the international mechanisms of accountability make it seem desirable to extend the domain of accountability by empowering domestic courts to act as agents of the world legal system. Even if there is no consistent application of Universal Jurisdiction, it still leads those who might be prosecuted to alter their travel plans to avoid even the complication of waiting for a complaint to be dismissed.

The idea of self-determination was gradually given credibility by international law, and it lent strong emancipatory support to movements of liberation struggling against a West-centric world order. Latin American countries used international law creatively, both to limit the protection of foreign investment by establishing the primacy of national sovereignty in relation to natural resources, and by building support for the norm on non-intervention in internal affairs.

As matters now stand, the combination of genocide, as conventionally understood, and crimes against humanity, seems sufficient to cover the criminality of political leaders, and the lethal consequences of totalising ideologies.
