The Germans don’t want a Brexit, but if it happens, they want to be sure that it is painful for the British, and they also want to be sure that it won’t upset the existing political consensus.
I think that the disaster for Theresa May, particularly in context of the German dogma for austerity, has shaken the German establishment, which is why Wolfgang Schäuble is now talking about how all will be forgiven if Britain decides to forgo leaving the EU:
German Finance Minister Wolfgang Schaeuble said that the U.K. would be welcomed back to the European Union if the British decided they no longer wanted to quit the bloc.
French President Emmanuel Macron also said the “door is open” for a return, but warned that it would be much harder to achieve once negotiations have started.
In his first public comments on the matter since the U.K. election, Schaeuble said that “it’s up to the British government to take their own decisions” on Brexit. He said he had discussed the surprise election outcome with Chancellor of the Exchequer Philip Hammond the day after the vote, and concluded that “we have to leave them some days” to decide on the way forward.
Asked if the government might reverse its decision to quit the EU, he said it “would not be helpful” to speculate whether that will happen or not. “The British government has said we will stay with the Brexit,” Schaeuble said in the interview during Bloomberg’s G-20 Germany Day. “We take the decision as a matter of respect. But if they wanted to change their decision, of course, they would find open doors.”
I think that they are afraid that if Brexit happens, and Labour ends up in charge, it won’t be a complete clusterf%$#, and could lead to other countries to pulling back from the EU.
