What the EU could learn from the Athenian Empire

The EU has regularly been likened to the Roman Empire. But its current direction suggests that the Athenian Empire (478-404 bc) is a better parallel.

The EU began as an attempt to unify countries economically after the second world war. By slow accretion of powers via the single market, Maastricht, the euro and finally Lisbon, the EU became, drip by drip, a full political union run by an unelected central authority, which now threatens to end vetoes and intervene domestically, suing member states with whose policies on immigration, civil rights, freedom of speech etc it disagrees.
