The obvious solution is that Russia alone can't knock out the dollar. But with Russia taking this action, the next step is now to get Central Asia on board.I still don't understand how the rouble currency exchange mechanism solves things long term. America and Europe can continue printing dollars and euros and get Russian oil and gas in return. If there really are western sanctions on Russia then you will be limited to what they can spend those dollars/euros on.
Unlike China right now, Russia is in a much better position to decouple from the west. The number of things that Europe produces that China or Asian countries can't is diminishing.
Central Asian countries should be incentivised to start taking actions on dollar usage. Incase any of them says no and starts sidedealing, they should be destroyed and forced to hand over their resources.
Sorry, but no sorry. This is about toppling the US, we don't have time to play with these minions. Either smell the coffee and follow the trend of the times, or get blown off by a bazooka.
I am not worried though, with Russia on board (after being forced by the West lol), Central Asia will soon follow. The combined China-Russia pressure is too great for them to resist.
Simple. Russia was first, next its Central Asia. With these 2 secured, China's position will be significantly strengthened versus the US.
