Sarkozy obviously didn’t mean it. He threatened, in effect, to pull out of the EU in order to save the EU—because the EU IS FRANCE, before any other country.
But there was that anonymous, unsubstantiated rumor that Germany might pull out of the EU. I think Germany only joined because France blackmailed them: Join the EU and we’ll cover you for all that wicked NAZI past of yours. But Germany is NOT happy about wrecking their economy to save the feckless Greeks and others, and Merkel’s government may be brought down because of that anger.
to paraphrase and old joke.......
You know the difference between a good friend and an idiot? A good friend will bail YOU out of jail; an idiot bails out your whole country with his credit card.
