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.

The British leadership has acknowledged that it only became possible to end the violence in North Ireland when it stopped thinking of the [Irish Republican Army] as "a terrorist organization" and began treating it as a political actor with genuine grievances that deserved to be addressed.

It may be that there is so much ambiguity and ideology attached to the term 'terrorism' that it is best to avoid its use altogether, as it is likely to be twisted in public discourse to demonise the enemies of the established order, while exempting state violence from legal and moral scrutiny.

Since Israel would rather re-experience Masada than renounce the core Zionist objective of establishing a Jewish state, the only one-state "solution" on the horizon of realistic possibilities is an Israeli "one state" that fulfills the messianic nationalist ideal embraced by deep Zionism, likely consisting of completing the expansionist process of recent years by incorporating all or most of the West Bank, casting Gaza adrift, consolidating control over Jerusalem, and transferring as many West Bank Palestinians as possible to Jordan.

It was a step forward to charge Pinochet with terrorism, and to acknowledge that the essence of the crime is the use of political violence to induce great fear in society and against those who are innocent, and not just such violence that is directed against the state by opposition groups.

The main challenge is what to do in the face of double standards. Those who should be rendered accountable under international criminal law, the Kissingers of this world, enjoy de facto impunity, while those who come from countries that have long been targets of hegemonic abuse are used as poster children of accountability.

America is perhaps best viewed as an 'authoritarian democracy' within its own territory and as 'a global state' of a new kind when considered internationally.
