I have some thoughts, some scepticism, some questions. First, some quotes from the article:

Ukraine has not claimed responsibility for the strikes.

…the Estonian government has firmly denied the claims.

…the closest distance between the Russian city and Ukraine is about 310 miles. This would have required the drone to fly through the airspace of Belarus. Avoiding Belarusian airspace could extend the journey to 700 miles or 435 miles, depending on the route.

However, Ukrainian drones are reportedly able to fly to distances up to and beyond this.

…reports suggested Ukrainian "Beaver" drones could have been behind attacks on Moscow, which are believed to have a range in excess of 620 miles.

In June, a spokesperson for Ukrainian state arms producer Ukroboronprom also posted on Facebook that it had successfully tested a drone with a range of 1,000 kilometers (620 miles).

Russia blamed Ukraine for other drone attacks overnight, which caused authorities to close the airspace over the Moscow and neighboring Tula oblasts.

I wouldn't be so sure that Estonia launched these attacks. I wouldn't be surprised to find that Ukraine (with US support) 'secretly' launched the drones from Estonia. Although it would apparently be possible to launch those drones from Ukraine.

It's in some Ukrainians' interest to find a way to get NATO more deeply involved before the hints that NATO is losing interest become more explicit, vocal, and practical. But I can't see how it would be in NATO's interest to let Estonia get involved like this because it would drag the whole of NATO into it. If NATO gets directly involved, the whole of NATO is fair game. Are we to believe that:

1. The US thinks Estonia could attack Russia and that Russia would only retaliate against Estonia?
2. If (1) were true and Russia would only retaliate against Estonia that Estonia would be stupid enough to sacrifice itself for the rest of NATO? After watching what Russia has done to Ukraine? I know libs are oblibious, but…

One possibility is that someone in Ukraine 'persuaded' someone in Estonia to make this happen or allow it to happen. Considering how corrupt all capitalists are, this is not unimaginable.

I wouldn't be surprised to learn that whoever did this was behind blowing up Nordstream II.
