But what was the practical alternative?
Do you really think that another 40 years of the mixture of scepticism
and luke-warm commitment from the UK was in anyone's interest?
So go ahead and trigger Article 50 already for Pete's sake!
Get off the stove, you'll likely cook for rather a long time otherwise — and incidentally, unblock the situation for the remaning 27 EU member states, so everyone can start the process of moving on from the UK and it's politics-of-identity in relation to Europe.
Take the hits. Find out what's on the other side of the mirror, for better or for worse. It should be what the British voted for after all. (Well, not the Scots or the Northern Irish, but they probably should leave in a UK break-up anyway.)
Personally, I've thought for a long time that the UK cannot remain the EU if a majority of Britons are aganist it, not without doing its democracy a serious nuisance.
The question of course might be if the British are against the EU for any good reasons at all, if they even know why they are?
But it matters not in the end, IF they oppose the EU.
So the UK should leave. Unless the British have changed their minds? Do they even know today?
That's also the kind of outcome these kinds of referenda tends to produce. Very large, peed-off minorities that the marginally larger majority still have to relate to. About things that might actually matter. Just telling them to sit down, shut up, and suck it all up should ideally be sufficient. It's just that in itself that can make some people change their minds about it all.
