I can only hope that Trump comes to realize the grave dangers of adopting a policy of confrontation toward Iran. Among these dangers is the likelihood that hardliners would again gain the upper hand in the governing process in Tehran, and the moderates who have sought to end national and regional tensions would be marginalized, or worse.

I do think there is an enhanced awareness of insecurity and vulnerability that induces anxiety that creates pressure on teachers and administrators to offer simplistic explanations and to be resistant to expressions of attitudes that can be viewed as unpatriotic, which is further interpreted as applicable to any tendency to challenge the government when it claims to be acting overseas to avoid repetitions of 9/11 or to encroach on domestic freedom to identify suspicious persons and behaviors.

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.

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.

Hamas retains the right to defend Gaza by the use of the weaponry at its disposal, and is thus not committed to nonviolence, but it does offer the possibility of greater peace and stability for both Israelis and Palestinians if the label of "terrorism" was abandoned and the search for accommodation was commenced in good faith.

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.

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.
