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.

It was a step forward to charge Pinochet with terrorism, and to acknowledge that the essence of the crime is the use of political violence to induce great fear in society and against those who are innocent, and not just such violence that is directed against the state by opposition groups.

It is on balance desirable to encourage Universal Jurisdiction, and to create pressure from below to make application of such jurisdiction as consistent as possible. I think this will act as a deterrent in some situations, although this impact will never be acknowledged by those affected as it would only embolden civil society to intensify its pressures.

At present, the United States, with over 700 foreign military bases, navies in every ocean, a programme to militarise space, and drone bases planned for all regions of the world, is increasingly perceived in relation to its hard power diplomacy, a threat to political independence and stability for many countries.

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.

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.
