Did this truly mean a £1tn budget political behemoth with its own lawmaking bodies, courts, parliament, maybe one day its own military, its own anthem and currency?Yes, it was! The EU was conceived as a way to prevent war (political alignment) through economics and trade.
"[t]he coming together of the countries of Europe requires the elimination of the age-old opposition of France and Germany ... the solidarity in production thus established will make it plain that any war between France and Germany becomes not merely unthinkable, but materially impossible."
Schuman declaration, generally regarded as the founding text of the EU.
1950.

The main reason why peace exists in Europe is not because of the common market or EU coming to exist post-WW2. It is because the main threat posed to Europe was the USSR/Russia and that threat has always been kept at arms length by the creation of NATO and expansion of nuclear weapons.
Again, I am not against the EU, I am just skeptical of its ability to do exactly what it was created for and if it can't do that then who can even question it? The proof is in the pudding because despite it being a trading bloc its economic and monetary policy is a disaster and has been for 20 years.
The European economy is now dying in the midst of German economic failure so what is the real benefit of showing solidarity or being further integrated into misery and demise? Or is the argument really that we're always going to be part of Europe else sink on our own ship so let's jump onto their ship and sink with them instead?
