> That article doesn't disprove a microwave attack at all, it just says there is no known public evidence that matches up with what is described.
I can not disprove that there is a magic man in the sky. Or a teapot revolving around the sun. [1]
The burden of proof is on the person making the claim not the other way round. Yes, lack of evidence is enough to reject it. Not to mention that the claim goes against established scientific knowledge and therefore would need some serious evidence for it to be taken serious.
> Even going back to the 60's there was stuff done in spycraft that would seem implausible to most people even today.
There is lot's of things we do not know but that does not make a good argument for the existence of something.
> A relevant example is the use of microwaves to activate a passive antenna through walls to eaves drop on conversations (look up "The Thing Listening Device). Again this was done many decades ago. Not too far fetched to consider that maybe Russia intelligence services found a way to weaponized microwaves.
Not really, there is no clear quantitative development patch from The Thing Listening Device to the Havana style microwave attack.
Now we know the hypotheses requiring the fewest assumptions to be more likely true. [2] So what is more likely?
The whole Havana Syndrome is fabricated propaganda that is typical and in line of many similar cases of proven lies?
Or that Cuba has some advanced secret technology that even the US has no access to and that they are using on US diplomatic personal without any good motivation. In fact it will hurt their reputation. So we need to also claim that they are irrationally evil.
