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.

Human rights and international criminal law both illustrate the contradictory potential of international law. On one level, the imposition of human rights norms is a restraint on interventionary diplomacy, especially if coupled with respect for the legal norm of self-determination. But on another level, the protection of human rights creates a pretext for intervention as given approval by the UN Security Council in the form of the R2P (responsibility to protect) norm, as used in the 2011 Libyan intervention. The same applies with international criminal accountability.

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.

There are degrees of incompatibility, and there are more factors relevant to upholding democracy and human rights than the operation of neoliberal markets. Perhaps this point can be initially made by reference to the decline of democracy and the erosion of human rights within the United States since the 9/11 attacks.

It should be appreciated that if the arrangement on Iran's nuclear program collapses after being so patiently negotiated, and successfully implemented since 2014 despite the intense opposition of Netanyahu's Israel and its American loyalists in Congress, it would be widely perceived around the world as a huge setback in the search for regional stability and the struggle to prevent any further spread of nuclear weapons.

With Islamophobic tendencies in Europe and North America it is quite possible that Islamic leaders could be charged with 'political genocide'. An extremist American pastor in a small Florida church held a trial that convicted the Koran of encouraging the murder of non-Muslims and of being responsible for the 9/11 attacks. It is this sort of outlook that would be encouraged to claim that Islam embodied 'political genocide', a development that would have many negative effects on inter-civilisational relations within and among countries.

As matters now stand, the veto seems inappropriate, given the absence of any deep ideological split between major states, and definitely constrains the war-prevention mission of the UN. Similarly, the present permanent five are out of touch with geopolitical realities, and constitute a remnant of a West-centric world order, casting a shadow of illegitimacy across the activities of the most important organ of global policymaking in the UN System.
