Yes, exactly. I still think it's possible, but if the (assumed real) afflictions continued long after public reports, which have obviously been out for many years, I guess that more or less settles the intent question. And if they're doing it elsewhere, not just Cuba... intent.

But also... the intel agencies know what it is. I'm about 99% certain that they're about 99% certain what's doing it. If we can think through it here even somewhat well, and they've got teams of people working on it, even part-time, presumably they can e.g. build a device to detect a microwave source (or lack thereof). Nor would it be hard to detect ultrasound or sub-sonic acoustic stuff.

I think the press release is "we'll pretend we don't know exactly what it is to give you one last chance to fucking stop it". And:

Still, it remains unclear why it took American officials so long to acknowledge the problem, and why they still show no sign of having a plan to solve it.

Nah I don't buy that. I think releasing the amount of info in the article is part of the plan to solve it. I dunno why else intel agencies would go forward with this. You're not gonna hear stuff like

U.S. officials told 60 Minutes that a senior U.S. Department of Defense official was targeted as recently as July 2023 at the NATO summit in Vilnius, Lithuania

otherwise.

I agree that suspicion is always warranted when it comes to our intel agencies and Russia's, but I don't know what U.S. national interests would be furthered by lying about this. The idea (mine, just now) that this is a psyop designed to make MAGAs realize that Russia is bad has me giggling though (edit: I mean because you'd basically need to make Putin kill Trump live on camera in Times Square to change their minds, at this point)
