Indeed.
I used to think the thing the UK should congratulate itself on was its transition from head of the largest empire the world had ever seen, to equal member of a powerful, mutually supportive bloc.
We could have just fallen by the wayside as a decayed, irrelevant ex-imperial power which had lost its tributary states. Instead we'd got over ourselves, been pragmatic, re-engineered ourselves to be a modern nation, and settled to a realistic, smaller but still valuable place in the world.
Or so I thought.
Now our sepia-tinted mythos of greatness has been used against us, by ourselves and by outsiders who will gain by our decline.
By constantly harking back to our glory days – while glossing over the embarrassing fact we were dependent on our Empire – we've puffed ourselves out with hot air and fooled ourselves we really are that big and can once again make it alone.
Wrong. The UK never had to stand alone; we could always answer "You and whose army?!" with, "Erm, look behind you..." at India, Australia, Canada, large swathes of Africa, the Middle East... And it was as true economically as it was militarily.
Now. Well. We really will be alone. And having lost both our families, we're busy pissing off our friends.
I'm not impressed with us.
