Please reread what you are saying here. I kind of understand that you are arguing that these moves are all 100% Ukraine, with no NATO involvement?

Seriously?

When I ask myself: "how can a country with no navy impose a naval blockade?" The answer is clear: it cannot.

Rather, the more logical and likely answer is that NATO is launching and controlling these attacks, probably from Romania. It is NATO that has the ISR and tracking capability, as well as the weapons systems delivery capability.

The Russian vet is correct: as long as Ukraine has a plausible launching place on the Black Sea, they can always claim full responsibility, and their cheerleaders like you will echo that narrative.
