In their recent open letter to Chancellor Angela Merkel, the five distinguished economists Thomas Piketty, Jeffrey Sachs, Heiner Flassbeck, Dani Rodrik, and Simon Wren-Lewis portray the eurozone "a beacon of hope". I do not agree with this description. The eurozone remains a historical mistake as long as the EU is not an independent political and military union.

For basic guidelines on the EU itself as "a beacon of hope", please study The Manifesto of Ventotene and the draft constitution from 1984, which you can find at http://www.spinellisfootsteps.info
