There is no way for anyone to make Russia Completely irrelevant. The idea is to ruin the standard of living enough for their people for them to consider political change, and force them to spend far more money than they want to on defense, with NATO along the entirety of their border.
Russia has a declining population and this war is causing a brain drain of some its most capable people, who are fleeing the country to live somewhere with more freedoms and a better standard of living. Russia will naturally decline on its own and it will increasingly become a petro slave to India and China as they emerge. The West's land armies were largely created to blunt the Soviet / Russian threat. Right now we're getting the cheapest possible price to neuter Russia's ability to project power in Europe. We don't need Russia eliminated, we simply need them to be far inferior to NATO. This war is forcing them to burn through the arsenal that the Soviets and the Russians spent 40 years stockpiling. By the conclusion of the war their ability to invade any capable military power will be blunted for a generation. That's a win for NATO.
Remember, Russia has a smaller GDP than Canada. It's a huge country with 140,000+ million people (and declining) but it's seeing virtually no growth. It was counting on growing it's natural gas / oil relationships with the rest of Europe to help fund its growth. That's no more. Now it will increasingly rely on China and India to replace those exports and both of those countries will shrewedly exploit Russia, who needs them as buyers. Over the next decade, we're going to see Russia struggle, not thrive.
We're even starting to see the Russian pundits realize that this war is going horribly for them.
When it comes to Russian TV sometimes i wonder if what were seeing is Russian social engineering. We know these people are hand picked and the state has the final say on the message and ive seen too many videos now where one panellist basically points out the obvious reality, only to be shut down by the irrationality of the majority. Is this no more then state training, to condition the russian people to see the obvious reality and reason of their fellow russians as false and wrong? Basically conditioning the Russian people to see white as black and black as white? And also to portray the reality opinion as a fringe minority opinion?
The guy points out that at the peak of soviet power, it couldn't compete economically with the west. Today economically Russia is nothing compared to the west so its impossible to out compete them in terms of pouring material into Ukraine. I can't believe that all the other panellists around him are that dumb not see what he's saying. I mean when the host says Russia is more flexible today as if to suggest its better economically and industrially today then it was at the peak of soviet power, is outlandish. These are grown men, surely this has to be an act?
Then the thing about giving a town back, the guy says so your saying we lost thousands of soldiers to what give the town back? Basically pointing out how outlandish the statement is.
But i would hate to be a russian today who sees the reality, he must imagine his entire country has gone mad.
