Footage of a Russian drone strike on the Chernobyl nuclear power plant that took place last night

You missed the obvious one: Sending a message that they are willing to escalate.

The strike hit the "sarcophage" that was built to contain the ruins of the reactor that blew up in 1986.

The message is "we will risk large scale nuclear contamination". Remember how a few months back they used an ICBM w.o. a nuclear warhead for some missile strike, they could have done with a regular missile?

Combine the two messages: "We have the missiles"+"we will risk large scale nuclear contamination" -> "We are serious about the nuke business. Don't get in our way."

To cover up a nuclear strike?

That won't work, because it's possible to very precisely determine the origin of radioactive fallout by analysing the types and quantities of different isotopes in it. Also (above ground/water) nuclear weapon detonations do have very distinct optical signatures that can be detected by very simple instruments mounted on satellites, while underground nuclear detonations do have distinct seismic signatures that can be detected and located with the same equipment used to monitor earthquakes. For underwater detonations, I'm sure there are acoustic signatures that will do the same.

We should invent a brain jammer

That's the weird part.

I wouldn't imagine Ukraine would ever do something so reckless.

But Russia has nothing to gain, peace talks are about to start with heavily favoring Russia

So all I can assume is it could be a third party that doesnt want the peace talk to happen at all, and did this to further destabalize the situation?

I dunno it's just super fucking weird overall. Why chernybol of all things, no one, not even putin, would want that thing to start popping off... right?

That attack for all intents and purposes should be viewed by the world as no different than a failed nuclear launch, really.

And everyone is too pussy to do anything about it.
