The idea is for the US to not be able to shutdown CC transactions at points of sale in Europe on a whim. All cards in europe are dual-issued under Visa or Mastercard, and under a national card payment processor. In France, that's CB (Carte Bancaire). When you pay in europe, it uses the European network. Outside, it uses Visa/Mastercard.

So sorry, we do definitely get what this entails :)
