Continuous failures of ECB policy, the collapse of Greece under the EURO, the PIGS in serious trouble, add a totally uncontrolled mass refugee crisis, the entire EU project looks like an incompetent bureaucratic mess.
The damage is so great that Even China and Russia have managed to claim the moral high ground and quit rightly blame the crisis on the EU itself and NATO adventurism in Syria.
I do not think rehashing WW2 German collective guilt as a media spectacle is going to change the perceptions of anyone paying attention to this horrible situation.
