No. The lesson is really for the USA/NATO. Which depends on air superiority as their battle strategy.
If Russian air defence is even better than Ukraine (yes it is), then NATO will have to get on the ground with these guys, and it won’t go any better than the Counter-Offensive.
If it is so good why are systems from s-400 on down be taken down at large numbers by a few western weapons, and good number of the weapons Russians Air Force is designed to take down are failing
Big plus though they are pretty good at taking down their own aircraft.
Pretty soon no awacs for Russia and the Sam units and Russia aircraft will be scurrying
Russian air defense seems pretty weak based on the ability of Ukraine to launch long distance slow drone attacks on strategic targets in Russia.
