I don't disagree with where you take that, but of course the (willingly?) apathetic can still bask (not "
basque", doh!) in a "nuthin' to do with me" attitude, even if their country has all-but-wet actual boots on the ground, and their equipment is their by proxy.
It's still a matter of expanding you consciousness, but of course you're not just targetting the <Foo> embassy for that country's treatment of region <Bar>, but also trying to pivot the diplomatic/trade/treaty links of your actual government.
I mean, I'm technically letting who knows how many objectional links go unprotested that might well involve my energy suppliers/local-to-national governments/regularly visited shopping chains, etc. I could possibly be blissfully unaware that SupermarketCo's buying practices are reinforcing tribal tensions over on a completely different continent. And even if I'm then informed of this, might consider it not worth my while to unilaterally change my choccy-biscuit consumption, let alone daub a bedsheet with messages and wave it around in front of the local store.
I might well avoid doing the latter. Especially if someone else was already doing it. And perhaps this then had me I silently doing the former (or switched to DiscountLtd's own-brands instead, imagining that this was a more guilt-free alternative, with or without proof), and I'd end up doing practically nothing to help the situation by doing so. Because I'm less inclined to activism, or more inclined to apathy.
But it'd be good (if the cause were good... and perhaps that's subjective) for there to actually be actual protesters. Outweighing my own direct 'contribution' of merely no longer buying one packet of chocco-bisqui-cruncho-wafers a week. Which would hardly contribute even a downward-blip on the respective financials (and wouldn't even identify the reason for it, by the time the munged information hits any decision-makers). Someone who can (and will) get noticed properly is better.
The only properly thought through problems I have with these
particular protests is that while calls for divesting are amongst the more powerful legitimate messages they can make, any divest will typically just ensure an equivalent (slightly discounted) revest by any body that is in a position to do so but without pesky students ever really in their face enough. Caveats to "do what's right, but without causing different forms of harm instead" are far more difficult than merely dropping a hot-potato. (The dropping of all the Sackler Family philanthropic links from all kinds of institutions probably was never net-positive in alll the consequences, just a performative 'good' that led to scrabbling around for different sponsorship/funding/honourations to link up with, etc.)
And that it's only a few precarious steps from "protect innocent Palestinians" to "support the annihilation of the Jewish state", which probably the right-minded bulk of the protesters would not willingly take
on their own, but certain elements can move the mob's group-overton window into that easier than they ought to. Notwithstanding that denying the right to protest is a bad thing that one would hope never happens in "the land of the free", one should ideally be intolerant of intolerance (and no more).
Of course, heavy-handed 'authorities' can pivot the "just here to indicate my support for peace" people into "you're denying us our voice" reactionaries, as well, and doesn't do much to prevent the creep from protest (or counter-protest, where applicable) into riot (and counter-riot), which then makes it an issue that
does directly effect those who turned up, despite not being directly involved.
(TL;DR;, voices need to be heard, or we never hear the vital message. When the voices are suppressed or go beyond being merely legitimate opinion-stating, or both trying to be done at the same time, then it gets problematic. Square that circle however you can.)
