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.

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.

International law in its counter-hegemonic uses is very important in any domain where issues of legitimacy are significant, but is rarely able to have a corresponding behavioural impact.

What both the state and the capitalist economy oppose is an understanding of what might be called "the true nature of things" (using the phrase without metaphysical pretensions), especially injustices and exploitative practices.

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 In this regard, the UN has succeeded, as none of the big countries has withdrawn, and the Organisation has managed to achieve virtually universal membership of all sovereign states.

To be a hegemon is inherently ambiguous, usually implying some mixture of dominance and legitimacy, that is, being seen as contributing global leadership in a generally benevolent manner.

On the cautionary side, Universal Jurisdiction could be used to achieve some kind of ideologically motivated criminalisation of 'the other' that would discredit and derail a constructive effort to develop a credible meta-law that governs the behaviour of leaders of sovereign states.
