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.

Looked at objectively, it is clear that the overwhelming majority of civilian deaths resulting from political violence are produced by what should be understood as "state terror." Terrorism also serves as an excuse to avoid diplomacy and the peaceful resolution of conflict.

American special relationships with Israel and Saudi Arabia blind us to their dreadful encroachments on human rights, as well as confer impunity on their leaders with respect to accountability for crimes against humanity.

It would seem to be the case that pressure on Iran to acquire nuclear weapons is almost totally driven by their need for a deterrent capability to avoid the fate of Iraq, Libya. The use of American military force in Syria thus sends exactly the opposite message as supposedly desired to the leadership in Tehran - and to others. North Korea has been dealt with diplomatically because it has the bomb and might use it if provoked.

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.

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.

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?".
