Public support for Israel is steadily falling; this poll was published just a couple of days ago https://news.gallup.com/poll/692948/u.s.-back-israel-militar... and other G7 countries are moving to recognise Palestine. So will the administration's push to use pro-Israel reasons to censure and penalise the universities steadily get out of touch with what the public want and sympathise with?
Do you really think the Trump administration is committed to its pro-Israel position? If they flipped sides, how long would it take for 90% of their voters to adjust and be happy again?
To the point that you have people who have politics that derivates from a populist/nativist right wing historical current that was always virulently anti-Semitic, now being the staunchest backers of the current Israeli government.
In the post-9/11 era, hatred of Islam, putting an equals-sign between Jewish and Israeli, and smearing anybody on "the left" who criticizes the actions of the Israeli state as "anti-Semitic", and shoring up the Israeli state with massive financial support ... this is all an ideological bundle that is working extremely well for them.
And is allowing them to siphon off support from "moderate" American Democrat voters who share these biases but not the rest of their ideological bill of goods. It's actually allowed them to build a powerful base of support even when they're doing extremely controversial things.
