Sanctions barely work on small countries. They're but a nuisance for mid-sized countries and do approximately nothing to big countries. Russian economy is mostly autarkic - consuming overwhelmingly goods and services produced within Russia. Their exports are energy commodities, not consumer goods - energy commodities are the bedrock of the modern world - they'll always find a buyer at market price or slightly below. Their national debt is negligible. China is not going to stop exporting their goods there, and I don't see corporations like Apple/Google/Volkswagen/Toyota giving up such a large market just to make a point. Token slaps on the wrist for the few selected oligarchs who haven't secured British citizenship yet are laughable

We should be honest to ourselves - short of Western citizens dying on the battlefield, there's nothing of consequence the West can do. Russia exploited our weaknesses really well - our irrational hesitance of nuclear energy, our greenwashing of natural gas, our love for petrol-guzzling SUVs, kowtowing of our financial system to ultra-rich, profit-uber-alles of our corporations, hypocrisy of our diplomacy, etc.
