A philosopher in Israel writes:

In the days after the attack, several students at universities in Israel were suspended or expelled without hearing for showing support for Hamas. That is fair enough – such support for terrorism is illegal under national Israeli law in any case.

However, this soon expanded to students who expressed support for the Palestinian cause or against the siege of Gaza in general. (See https://www.adalah.org/en/content/view/10903) 

This is all by way of precursor to establish that what occurred today is not an anomaly but part of a broader pattern of the stifling of speech since October 7th. 

A Full Professor of Law, a Palestinian, Nadera Shalhoub-Kevorkian, was sent a letter by Hebrew University's President Asher Cohen and Rector Tamir Sheafer harshly criticizing her and strongly pressuring her to resign because she was one of 1200 academic signatories to an open letter here.  The President and Rector's letter said the open letter comes close to criminal "incitement" and "sedition":  Download Professor Shaloub Kevorkian Letter

It seems that the President and Rector's problems with the letter concern (a) the use of the word "genocide" to describe Israel's actions in Gaza, and (b) the claim that Palestine has been occupied "since 1948". 

(I myself disagree with both of these claims: I am appalled by what Israel is doing in Gaza, but I do not think it rises to the level of genocide. Furthermore, I do not think it is correct to say Palestine has been occupied since 1948, as I mark the beginning of the occupation as occurring after the '67 war.)

However, both (a) and (b) are claims which are perfectly within the realm of reasonable scholarly debate, including among legal scholars. See here: https://twailr.com/public-statement-scholars-warn-of-potential-genocide-in-gaza/ 
and here: https://mepc.org/commentary/original-no-why-arabs-rejected-zionism-and-why-it-matters ) 

In my opinion, Nadera represents a canary in the coalmine for the future of academic freedom in Israel. I think it is important to speak up and make this known. 

Another Israeli academic tells me that the University leadership was under outside pressure to condemn the professor for signing the open letter.   Faculty, in law and other disciplines, have now sent a letter to the University leadership in response:

We read with amazement the letter that was sent to Professor Nadera Shalhoub Kevorkian and we also read carefuly the letter which she signed. The letter calls for a ceasefire and it also contains harsh accusations against the state of Israel. Many of us object vehemently to the letter signed by Professor Shalhoub-Kevorkian but we do not believe that signing this letter can justify the harsh reaction of the university President and Provost. Certainly, we do not think that Professor Shalhoub Kevorkian should consider resigning from the university. We believe that her letter should be protected by freedom of speech and we hope that in the future the university heads will protect the freedom of speech of the staff at the Hebrew University.
