It is possible that, in fact, Trump's call for "America First" (despite evoking unpleasant recollections that such a phrase was the invention of those in the 1930s harboring fascist sympathies) and a positive relationship with Russia, might lead [to] a more relaxed global setting.

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 In this regard, the UN has succeeded, as none of the big countries has withdrawn, and the Organisation has managed to achieve virtually universal membership of all sovereign states.

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.

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.

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.

If Trump were to go ahead with a renewed policy of hostility toward Iran, it would immediately raise tensions, and could quickly escalate in the direction of war, with grave dangers of producing another Syrian tragedy of massive displacement and prolonged strife that could cause turmoil and disruptions throughout the entire region, and give rise to a new cycle of extremism.

I think the impacts of 9/11 on academic freedom vary greatly depending on locale and time (softening with the passage of time), and even within the same community, and likely within the same schools. This variability makes it difficult to offer generalized responses without accompanying caveats.
