30 milligrams of high explosive is enough to open your daughter's skull, or, more relevantly, your commanding officer's daughter's skull, and there are a thousand ways to deliver it to her if she can be tracked: in pager batteries, crawling, swimming, floating, waiting for ambush, hitchhiking on migratory birds, hitchhiking on car undercarriages, in her Amazon Prime deliveries, falling from a hydrogen balloon in the mesosphere, and so on. And if 30mg is too much, 2mg of ricin on a mechanical ovipositor will do just as well.
All of this is technically possible today without any new discoveries. At this point it's a straightforward systems development exercise. And you can be sure that there are bad people working for multiple different countries' spy agencies who know this; they don't need me to tell them.
While we are talking about flying drones, we are not far off from Slaughterbots becoming reality.[0] Why bother with surgical assassinations if you can blanket entire regions with with swarms of autonomous seek-and-destroy explosives?
After all, as last two years have so amply demonstrated: people are fine with genocide.
Technologies are morally agnostic: a knife, a rifle, a piece of cryptography, they all work equally well for the noblest and the most nefarious purposes. It's the humans' task to structure the society in such a way that good uses of technology mostly dominate evil uses.
Why bother? For the same reason to bother with surgical assassinations if you can blanket entire regions with nuclear fireballs. Radioactive wastelands are unprofitable! This is a general problem with genocide: it only gets you land, and since the Green Revolution land is abundant. Protection rackets, on the otehr hand, are highly profitable, but only with some exclusivity; if extortionists multiply, the unique Nash equilibrium is multiple gangs that collectively demand many times the victims' total revenues, resulting in ecological collapse.
More generally, the threat of violence is only effective as a form of coercion when you can credibly withdraw the violence as a reward for compliance. Violence provides no incentive to comply to someone who believes they are just as likely to be a victim whether they comply or not.
But swarms of autonomous seek-and-destroy explosives are plausibly the most effective way to provide that surgical-assassination threat, perhaps combined with poisons, solid penetrators, and/or incendiaries. The Minority Report spiders (not yet technically feasible) or a quadcopter can be enormously more selective than a GBU-57, a Hellfire missile, or even a hand grenade, and can choose to avert their attack at the last millisecond upon the presentation of properly signed do-not-assassinate orders, even if long-distance communication is jammed.
Hence, I suppose, important figures will eventually disappear from the public eye. Definitely, a president or a governor must be present in person at many events. But e.g. CEOs of military contractors, or even key scientists and developers in certain fields, may start to fade away, turn pseudonymous, and virtualize, now that remote work and videoconferencing is normalized. They would still be somehow trackable as normal citizens, but their visible connection to their work would be severed and kept an utmost secret, literally a life-and-death secret.
This would be good news for national defense, but bad news for any dissenters who cross any powerful-enough entities for those to consider an assassination or at least blackmailing. Unlike a hitman, a hit drone can be completely and safely destroyed beyond recognition within an hour, by burning it and grinding the ashes.
Also, precisely delivered non-lethal means could be quite effective, and hard to track. Inject or just spray a bad virus to disable your opponent for several critical months. Spray a potent allergen if the target is allergic. Inject some LSD into politician's bloodstream an hour before an important meeting or speech. "Innocent" stuff like that.
Last two years? Try last few decades at the very least. People only care about the war in Gaza more because it's controversial. For non-controversial cases people just agree it's bad but shrug their shoulders.

This also explains the more prevalent ignorance concerning the other two genocides of your list: they are simply for away from the place the respective person lives.
Yes, privacy is a question of civil defense in the drone age. But the existing crop of states will never acknowledge that; their structure and institutions presume precisely the kind of mass databases of PII that create this vulnerability, as well as institutional transparency for public accountability. This makes them structurally vulnerable to insurgencies that expropriate those databases for targeting. The existing states will continue to clutch at their fantasies of adequately secured taxpayer databases until their territorial control (itself an anachronism in the drone age; boots on the ground can no longer provide security against things like Operation Spiderweb) has been reduced to a few fortified clandestine facilities.
Things are going to be very unpredictable and, I suspect, extremely violent.
