I am a great admirer of academicians and good universities, and Israel has an abundance of both. But, as you know, boycotts of universities (days of the cold war) are usually for political reasons, not academic. Just as international boycotts by unions, journalistic federations, military exercises, etc., are not for professional reasons. These entities want to protest the policies of the Israeli govt. I know of no precedent for your contention that violations of international law must have two sides: except for perpetrators and victims. When the UN declared Israel in violation of resolutions 242,452 and 465, and 4th Geneva Convention articles 49,53 and 147 and thus in commission of a war crime, one would have to wonder who the other side could be. Palestinians did not refuse to withdraw from territory they captured in 1967, nor did they annex Jerusalem. Interesting to note: no Jew addresses the issue of violation of international law: always some peripheral issue.
