Those are the same who pay for the campaigns of the lawmakers who approved for more weapons to be sent to Kiev, so I think your theory does not make sense at all. If those in charge of much of the money wanted Russia to get its way, then they would not continue to fund the election of officials who are willing to continue to send weaponry to Ukraine for her defense from the invaders. That is what Russia is, an invader.
Also, You cannot be serious when you refer to Russia as the future world economical and financial center of the world, Russian economy is extremely small, even countries like Italy get more money annually than Russia. It is a country which wants to be perceived internationally as a giant and powerful republic, like China, when in reality it is a pretty empty big and desolated country with many people living in misery and hooked to drugs coming from Afghanistan and the rest of Asia.
If Russia did not have the backing of China (an actual super power), it would be just like north korea, a second world irrelevant country with nukes.
Where do the money and weapons go? Many of them go to Russia throguh capture or on the black market.
The financial powers wouldn't have sanctioned Russia if they truly wanted to stop her. She has only become stronger through the sanctions.
A gun in the hands of a teenager gives the teen a lot of strength to fight off others, even if the otheers have guns. Russia has nukes.
What better place to relocate the finance center of the world than a small country with top-notch nukes? Russia has nukes for protection, and owns Siberia. She's just starting.
Under that logic the investors and the most powerful companies on the planet would be looking forward to establish their headquarters in north Korea, that won't happen only because it is a small nation with advanced nukes. It does not make sense in any way.
Also, because of the sanctions Russia has been selling oil and gas under the price of the market to clients in countries with a high rate of energy consumption, like India and China. I even recall India benefited from it by buying Russian oil and reselling at international prices to Europe and United States, that means Russia has lost significant amounts of cash and liquidity because it has started to get excluded from the rest of the planet. Again, it was not for China (which is an actual super power) the weak Russian economy would be already underground and with negative numbers.
Having nukes does not mean a country is a economically powerful country, even a banana republic like Cuba could have managed to have their own nuclear weapons with the backing of the Soviet Union back in the day.
