This one is about the money.
France, and also Germany, have had national policies of promoting their companies, even when those companies are selling to bad national actors. The French built Saddam’s nuclear reactor at Osirak that the Israelis took out.
Their beef here is over the loss of a $90 B contract, aside from any engineering and strategic considerations.
France was screwing Australia. Its product was lousy and wouldn’t be deliverable for years/ Australia was fed up, and France got what it deserved.
