Why? Primary sanctions didn't. The US and Europe effectively crashed out of Russia's economy for the most part; they lost access to Western banking, Western businesses abandoned Russia in droves, and the oil and gas sales to Europe that Russia is heavily dependent upon have been significantly reduced. Yet they seem to be doing fine, so what's left?
Also, why on earth would China walk away from trade with Russia? It's pretty clear the US-led world order of trade is falling apart and China hasn't been the one begging for trade deals over here, they seem fine to just write us off and go on about their business elsewhere in the world, I doubt they would have any compunction about doing the same to Europe if it came to that (which I doubt it will.)
Don't. Even if it's not a cult (it totally is) it's a scam designed to extract money from people. If you just want to give up a significant portion of your money and feel like you belong you're welcome to buy a shitload of weed and come hang out with my friends and I.
