Two missiles sent. The best evidence that it was an Ukrainian attack are the reports of the rest of the ships moving further away from Ukraine, as reported by US and verifiable by OS Int. That is a fuc**ng ton of money.
Remember those yachts being seized around the world... a couple of those is worth roughly as much as that missile cruiser. Isn't it amazing how during Putins reign "individuals" were able to amass such wealth but the state can't build any new warships of that size and is using 40-years old Soviet ships with defense systems that can be defeated by a Turkish drone.
Speaking of Bayraktar, a couple of weeks ago Kremlin claimed to have
destroyed 35 of 36 that Ukraine allegedly had, which is such an obvious nonsense (Ukraine never had that many; and definitely had more than one remaining). Since then they claim to have
destroyed a few more. Those
negative remaining drones must be some sort of spacetime anomaly, which would explain the spontaneous combustion of the ill-fated warship

Watch! Evidence of Putin having a hidden physics laws singularity generator coming from official sources (probably from the "Ministry of Dark Humor and Fantasylands") that allows them to destroy more weapons than Ukraine really had. How do you dare to doubt!

As far as I remember Sergei Pugachev, a former friend of Putin, said that the reason for the state of the army is the reason why they have all this wealth. Putin and "his people" sell everything the Soviet army had to offer and use the money for their own benefit. They even stripped electronics and sold it for scrap....
At this point, I would need proof that any of Putin's tanks actually carried electronics in the first place.

And what about Kramatorsk? I see everything quickly calmed down there after the serial number surfaced. Provocation failed? But there 50 people died from a missile strike with cluster munitions on their own civilians. An ugly story, it would be nice to deal with it and punish the perpetrators. However, I think that the direct executors have already been demilitarized, Russian intelligence officers in the field work well and Russian missiles hit right on the target.
Like I already said, these serial numbers doesn't prooves that missile belongs to Ukraine. Few examples. Here is Tochka U used by Ukraine in Snezhnoe in 2014:

...
The serial number only proves that someone painted numbers on that weapon at some point in time. As for the rest, if Putin had any real proof, satellite recording, or any real evidence it would already be there.
