My own sense is that if David Friedman chooses to live in Jerusalem, and quietly conduct diplomatic business from the now existing US consulate in the city, it will not be noticed very much. It will not be treated as a rupture with the past unless it is accompanied by other American encouragements of Israeli extremism undertaken with the clear backing of the White House.

In the Goldstone Report, Israeli perpetrators of possible crimes against humanity were made subject to prosecution and punishment, although the geopolitical leverage of the United States within the UN prevents implementation. At the same time, several African leaders are being prosecuted for their crimes against humanity and participation in genocide: a double standard of sorts, given the impunity accorded to the West and Israel.

The Goldstone Report establishes the credibility of the accusations directed at Israel with respect to its tactics used during the 2008 - 09 attacks on Gaza, but was not able to facilitate the next step that would have involved activating accountability mechanisms either within Israel or at the level of international society.

On the one side, I welcome prosecutions of individuals such as Pinochet, and would welcome the indictment, prosecution, and punishment of Kissinger. On the other side is the geopolitical reality that only those in the global South are likely to experience the impact of Universal Jurisdiction.

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.

When I told my mother that I have to give a talk, and was debating what could I possibly say to non-mathematicians, she said: "You got what to wear?".

Doing something, however pathetic, is psychologically better than doing nothing. In the current political environment - that is, with no more Cold War tensions - the tendency is to counteract the feelings of fear and vulnerability with a variety of military, paramilitary and police measures, despite the reality that this kind of excessive reliance on force in many ways intensifies the very problem it is purporting to solve.
