I wouldn’t disagree that Russia has corruption, but I don’t think that means much. It’s much less corrupt now than it was when Yeltsin’s government let the Western shock therapists come in and plunder the country. Putin’s government kicked them out. Ukraine is famously the most corrupt country in Europe, though reports about that mysteriously stopped in 2020. Just based on the cost-plus model of our military-industrial complex alone, the US is very corrupt.
And I wouldn’t disagree that Ukraine’s drones will continue to be a challenge for Russian infrastructure. They can only reach so deep into the deepest state landmass on Earth, though. Eastern Russia is largely barren, though, and I’m not trying to discount the drones by arguing it isn’t.
