I'm surprised that our political class is having police and the national guard beat up students protesting, I think I may need to reevaluate some things. Among my concerns and self reflection, and these aren't meant to be in any order:
1) It seems like bad political strategy. Punishing the students validates their protests. Isn't that obvious? Maybe I'm confused? Given that our leaders have different priorities, they'd be better off (in terms of their position) ignoring the students.
2) A while back someone here posted a link, I forget who it was, by an intelligence community leader suggesting the Gaza crisis could radicalize people. I think I dismissed it. I think that our leaders don't dismiss it. If people start questioning official narratives on Israel and Palestine, they might question other things too. But clearly if students at Columbia are willing to be kicked out of their apartments for this, are willing to lose their semesters, I was wrong, there is a risk of radicalization.
3) It does seem noble that Americans are protesting out of empathy. At this point, almost none of us living here are personally affected by the war, people aren't protesting to avoid being drafted, etc. They're protesting purely out of empathy for people half a planet away. They're risking their entire futures, they could be blacklisted by employers, etc ... I think the students know this has the potential to destroy their future careers ... To cry out an injustice half the world away.
4) Another cost is this makes the USA look bad. The whole world knows what Washington would be saying if police in Tehran, Moscow, or Beijing were acting like this, I'd have thought that'd be a disincentive but I guess not.
