When I read the news that the Ukrainian army is unable to repel the attacks of the drones that Russia acquired from Iran, it becomes clear to me that the Ukrainian surface-to-air defenses are very weak or non-existent at all.
They're hitting ~80% of those drones, which is quite good for "non-existent" air defense.
Russian air force proper doesn't ever try to enter Ukrainian airspace anymore, choosing to launch low-accuracy missiles from Belarus or deep inside Russian territory, which I think tells us something different than you assumed about the effectiveness of Ukrainian air defense.
The same thing when I read the news that Britain is training the Ukrainian forces on its soil before redeploying them to the battlefield, it becomes clear to me that this army is inexperienced in wars and it is hard to believe that it wins successive rounds as the loyal media wants to portray us.
Ukrainian soldiers training abroad seems like a major advantage over freshly mobilized Russian forces barely training if at all. Even if you believe Russian military training is on par with British, that's a wash at best.
Russia is putting pressure on Ukraine from several sides, not only militarily. The targeting of vital facilities (airports, power generators, warehouses for goods...) greatly affects the military support of the Ukrainian army, to which the allied countries are unable to provide adequate assistance.
And Ukrainians are shelling actual military targets like ammunition depots, supply routes, as opposed to Russians trying to hit civilian infrastructure and cause a humanitarian crisis. Again, seems like a significant military advantage for Ukrainians.
Not sure why you're still trying to twist this into some major media conspiracy. There is clearly a shift of momentum compared to the early months of the war and Ukrainians have been gaining ground for the last 2-3 months. Even Russian side admits losing Kharkov region and retreating from Kherson. Are the Russians also in on the pro-Ukrainian conspiracy?
