Based on a comment I made here.
In the EU, lack of accountability is a feature, not a bug. If you claim that nationalism is the great problem of European history, and define nationalism as a popular passion, then blocking responsiveness to popular passion becomes "the solution". Which is nonsense, the great problem of European history is unaccountable power, not "nationalism" as such. Precisely which problem the European Central Bank (ECB) is demonstrating daily.
