They can do that to Americans. Harder for the rest of the world. How is the US going to monitor CIPS payments? How will they jail someone who never goes to the US? Just how much global jurisdiction is the US claiming?

In practice, the key ways that the US exerts influence outside of its own borders: (1) Sanction the company, which means any other company that does business with that company can also be sanctioned. (2) If enough companies are evading sanctions in a single country or the govt is helping those companies, then threaten to cut the country from USD settlement with the Federal Reserve, e.g., no USD FX allowed. That pretty much screws most economies. The "long arm" of the US govt is very, very, very long!

To be clear: I am not saying any of this is fair (or legal); I am only explaining how it works.

How is the money going to end up in a US account via CIPS?

> How will they jail someone who never goes to the US?

The same way they "jail" UN-appointed judges that go against their masters' interests: de-platform them from all US-controlled payment and software platforms.
