Uh, Russia will be too broke to continue funding their war offensive in Ukraine, and then if they try to continue it anyway they'll be too broke to continue functioning as a nation. That's kind of the point of sanctions. Did you read the article?
Payment scuffles between Russian companies and Chinese banks have escalated in recent weeks, with nearly all Chinese banks stopping transactions with Russia. Some banks have even returned payments for goods that had already been sent to Russia, out of fear of being targeted by sanctions, a Russian media outlet reported.
Drop the war, investors return, everyone is happy. If they want to continue the war they better start checking their couch cushions for rubles. That's what the sanctions are for, that's what they do. It's a lever to pull to convince Putin to back off his warmongering without resorting to direct violence against Moscow and, undoubtedly, innocents caught up in it.
Funnily enough I can speak to multiple people; nice of you to chime in like that though.
Sanctions, such as those on Iran, saw one incremental change (which I acknowledged with "that's one... example" and gave context). I hadn't checked the other example yet. Thanks for white knighting like a twat, really helps.
Edit: the Sudetenland example is not of sanctions, but lack thereof, so not an example of how sanctions have worked.
