You mean VISA cards, with a few extra apps (that's what, say, Worldcom is, an app on a VISA card) the data sent over Cisco equipment to IBM compatible servers with encryption via chips developed through VISA by American manufacturers?

I still see some issues there.

Oh, and VISA had to demand Worldcom be moved to Switzerland, to prevent EU countries from let's call it "using it in negotiation" against each other.

And I'm going to go out on a limb here and predict that in a few years, or as soon as the Ukraine war ends one way or another, central banks are going to demand SWIFT moves out of Brussels as well. Call it a shot in the dark.

I get that it's become difficult to trust the US recently for the reason we all know. But you shouldn't forget: these institutions need to be trusted by every central bank ... and "trusted by every central bank" is not the EU either (well it especially isn't France or Germany, who effectively control the EU)

I think the EU (both as a union and as member states) are at risk of the USA doing shenanigans here, particularly due to Project 2025 cutting out the checks and balances that ought to slow down the Executive branch, where the USA moving as slowly as it normally would, would give the EU time to move.

But also, I do also think the various European governments are taking the threat of the US doing nonsense things seriously, and are doing the things to mitigate those risks as best as possible.
