And they do it when the US and NATO don't send enough money to Ukraine. That's why Ukraine can build nukes without the help of the US and NATO, if they want.

I see that you have pro-putin political views. Can you look at this video, please?

Inflation steals from average people who use that kind of money. In the US, the banking system causes the inflation. If people don't wake up to this fact, they will be conquered by the banking system. It doesn't have anything to do with Putin, except that he and many other nations recognize the banking theft of the US banking system.
When Russia uses the USDollar, they automatically lose to the US banking system. Same with China, India, Pakistan, any South American country, and all Americans in the US. Many countries have figured this out. Mostly, it's the American people who haven't figured it out, yet. At least not formally in big numbers of them.
The OP 'science talk' is part of what the banks use to cover this up. And people don't even realize it.
