On the contrary, historical perspective is essential in understanding the issues that the EU is going through currently. If the German leadership took a good look in the mirror, it would see that it is subjecting Greece to a replica of the Treaty of Versaille and, as a result, should expect similar consequences. The PR outfall of that debacle is probably what pushed the Brits to vote for exit.
What they are doing to Greece is actually much worse then Versaille. It has to do with the issue that Greece should have defaulted years (I was arguing this even in 2008) and change their government. Because of EU (EMU) logic this can not happen. So Greece is forced to change its government in the context of huge debt and even worse a flat demand curve (look at EU NGDP and Greece NGDP). Greece is about the only country that actually did significant Austerity but its not working. The EU should have let them default or take over their debt completely.
You are probably right that PR is the main issue. It was with 'Versaille' as well. German government PR is the main reason why you use 'Versaille' as an example of evil practice. Maybe the most successful example of PR in the last 100 years.
