They just took out 40% of Russian oil export capacity.
>They just took out 40% of Russian oil export capacity.
Yes, Ust-Luga and Primorsk. Very successful hits. Painful for Putin. Yet it isn't a knock-down. Russia is like a big drunk guy in a street fight - just delivering painful blows to him doesn't help, you have to deliver a knock-out blow, and unfortunately Ukraine still seems far from it.
North Vietnam didn't die of exhaustion, nor did Afghanistan (2x), Iraq.
For reference, it's likely Ukraine is making more medium cheap drones per year than Iran, the current boogeyman.
This war will end the same way, probably around 2030.
WW2 wasn't ended by capturing Berlin, it was ended because the German military was destroyed or surrendered as they were forced back towards Berlin.
By the time it fell, there wasn't an effective German military left.
>Both countries do the type of attack drone clustering you suggest
Ukraine still isn't completely there. They do attack Russia with up to 200 drones/day. They seem to never cluster more than a few, and the drones they are using are comparably small - 50kg warhead - and slow, 100+ km/h, almost always less than 200km/h. So they are easy to intercept/shoot down, almost never penetrate Moscow air defense, and do noticeable damage only when hitting flammable targets like oil/gas industry related.
