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.

When I told my son that I had to give a talk about my work to non-mathematicians, he warned me that regular people don't think like mathematicians.

I don't like to end my talk with a 700 million dollar loss, even if it shows the importance of Numerical Analysis.

After the Second World War, facilitating the establishment of the UN and aiding the reconstruction of Europe, the United States was widely viewed, at least in the West, as a benevolent hegemon. In the non-West, the US was often perceived as a supporter of the colonial powers in their struggle to maintain control over their colonial possessions, and was viewed far more critically, especially by emerging elites that were more inclined to socialist development paradigms than to the capitalist ethos favoured by Washington.

Historically, international law lent a measure of legality to the colonial system, and allowed the West to set the rules for participation as a sovereign state on a global level. It also protected the interests of foreign investment in countries of the global South even when these were exploitative, and deprived countries of the benefits of resources situated within their territories.

The capitalist priority is efficiency of capital and profitability, which is generally inconsistent with protecting the vulnerabilities of people and nature.

The fact that Universal Jurisdiction exists in relation to serious international crimes does convey two important aspects of the global reality: first, that such individuals would be held accountable if international law was applied without regard to geopolitics, and second, that there is enough ambiguity about the reach of UJ that it inhibits such individuals and conveys an impression of de facto criminality.
