The effect of Ukraine's drone attack on Russian airbases shows that they can attack anywhere in Russia, but only if they planned like a year or a year and a half before hand. And most of the aircraft destroyed were strategic bombers that are more relevent to NATO and USA rather than on battlefields in Ukraine.
In way NATO and US should be quite pleased that Ukraine managed to reduce Russia's strategic strenght, and may influence NATO's decision to increase arms shipment and monentary aids to Ukraine. However, the price paid by Ukraine is Russia's revenge in one of the most destrutive missile and drone attack.
On the ground, Russians are still pushing and gaining territories eventhough very slowly. Attacks on Russian airbases has little effect on frontlines.
As on drones, Ukrainians seem to be progressing onward to self-made drones rather than buying from outher countries, especially the suicide drones. I have just watch a CCTV reporting yeaterday with video footages on a Ukrainian workshop using several dozens of 3D printers making drone parts, with reported production capacity of 4,000 drones a month.
If they have several such workshops, they will have sustainable supply of FPV drones.
In a big picture, neither side can make fast progress if NATO keep on pumping weapons and money into Ukraine, this may be a long war.
