First, The US government launches economic war against Russia by cutting off access to their own money held in US and US-controlled banks.
Next, China and Saudi/UAE discuss pricing oil exports in Chinese yuan, while the latter refuse to speak with Biden.
Now Russia demands payment in rubles for its energy exports.
These are enormous cracks in the structure of the US dollar as world’s reserve currency, which is largely based upon its utility as the petrodollar.
That’s the plan.
Long term, this Ukraine conflict and our use of economic warfare will cause Russia and China to move closer together. It will energize the effort with BRICs: https://en.wikipedia.org/wiki/BRIC
Short term, we will inflict far more damage on them but we will also feel this since they are a major global world energy, wheat, fertilizer, titanium (aviation) and platinum (chemical/automotive) supplier.
