The Russian space program is also in dire trouble due to lack of funding and the failure to develop reusable boosters. The Russian capacity for satellite launches and space exploration are much reduced and are unlikely to ever recover their former strength.
Russia may end up occupying a substantial slice of Ukraine but it will have little economic benefit to Russia because, even now, she lacks the people and technical resources needed for proper development of her economic potential.
One reason why the US and Europe continue to support Ukraine is that the war and sanctions are diminishing Russia in the long term. That helps to reduce the threat that Putin and Russia represent to the West.
Your problem making this claim is that Russia is NOT behind an iron curtain. Russian vloggers put out videos daily. And, the ones I watch have said there is very little difference between life now and before the sanctions were implement. There has been some inflation but not nearly as bad as here under Biden.
The only impact sanctions have had on the average Russian is that it has hindered where he or she can travel.
That is beyond an ignorant contention.
Russia has, probably, as advance a military and space program as exists in the world. It's either us or them.
Unquestionably, Russia's manufacturing capacity is greater than the entire West combined as proven by Russia's 10-1 advantage in ammo and missiles in the war in Ukraine.
Russia's natural resources are unmatched.
A hatred that blinds one to reality is one that is dangerous.
