I once got a call from a bank, asking me to compute a mortgage, since their computers were down. This was a very depressing moment.

Any move by Israel to end the conflict with the Palestinians by unilateral moves - such as annexing the West Bank, delinking Gaza and declaring that there be no further diplomatic process - will lead to strong regional and global reactions, as well as intensify efforts at the UN and in civil society to brand Israel as an outlaw state dangerous to regional and world peace and guilty of criminal behavior.

There was a deliberate decision after the failure of the League of Nations to make the next attempt to establish a global political actor sensitive to geopolitical realities. The underlying idea was to provide major states, defined in 1945 by reference to the winners in the Second World War (now an anachronism), with assurance that they could take part in the UN without jeopardising their national interests. In this regard, the UN has succeeded, as none of the big countries has withdrawn, and the Organisation has managed to achieve virtually universal membership of all sovereign states.

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.

So far, the official definitions of terrorism have the role of demonizing the enemies of the United States and Israel, and of sanitizing recourse to indiscriminate force by both governments that causes widespread death of innocent civilians. This double standard is built around the current way in which the vocabulary of terrorism is being used in this country.

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.
