Two things, which on first reading seem bad, are in fact, good !
One, the Eurofighter debacle. The Saudis may not buy this heap of integrated product of a single happy Europe. Which may seem bad for the British defence industry. Hold on, what British defence industry ? If there is such a thing, how come British troops are being supplied with substandard ammunition made in Pakistan ?
The other is the Airbus Mighty Plane, that has had many orders cancelled because the project is running late.
These are the two flagships of European integration, designed by a team of people from across Europe, the parts manufactured across Europe and assembled in, I think, France. If they fail, as seems likely, the idea of an integrated Europe will take a mighty knock.
