#Russia is the one supposed to be sanctioned but it's US #banks that are failing and US suffering inflation¹ and #layoffs in the tech industry.
[1]: not technically #inflation but everyone calls it like that so you got the idea.
A little country like Cuba survived severe sanctions for decades and Russian economy is going better since the sanctions, the increased prices of fossil fuels due to sactions benefited them, and it was predictable.
Instead US no longer have the industrial capacity of the past, they have not improved infrastructures for decades, they have recently made up for the lack of fossil fuels with the highly dangerous practice for the environment called fracking.
US is not in a position to impose sanctions to a country like Russia that have resources and is part of BRICS together with China and India, two of the largest emerging economies in the world.
The failure of US banks is also a consequence of the sanctions on Russia.
If you want a rationale for such irrational behavior by US, to me it is hysteria due to the inevitable loss of dominance over the rest of the world and the birth of a multipolar order.
The result is just acceleration of an inevitable process.
