How much money did russia burn in that attack? …and for what? To train Ukraine to be the best at air defense out of any nation on earth? This will never win the war for russia, no matter how many they send at Ukraine. This is a bullshit strategy meant to buy time.

edit I just did a back of the envelope calculation, russia spent probably at least ~50 million usd in drones alone in this attack not to mention the cost of logistics and staging, is this really a “cheap” strategy?

What did the ~50 million do for russia in terms of building true power? This is just desperate terrorism.
