As a Briton myself, that "coming together" would be years of screaming, where incoherent irrational people with cruel and false beliefs outshouted the minority of thoughtful, ethical, rational people.
Britain is a tiny country with a fairly short growing season. For Britain to be agriculturally self-sufficient, an awful lot of Britons would have to go back to the fields, and they'd have to switch to a much more intensive agricultural style.
It might yet happen, but it means the death of Britain as we think of it.
Likely Scotland and Ireland would break off. I mean, Scotland is hard place to grow food...
I've written Britain off. For generations, the country has made the wrong choices over and over again. If they had a collective soul, we'd have seen it years ago.
Brexit appalled me in so many ways. The whole mechanism by which it happened; the relentless lying; the fact that Labour refused to authoritatively come out against the Brexit; that even after it was obvious how bad it was going to be, a new referendum on the actual terms was never allowed; that no politician of stature was willing to champion remain in the years after; that the monstrous Boris Johnson was elected; that the royals refused to act or even respond to this grievous, self-inflicted wound.
(A note if you aren't British: it's only a matter of custom that the royals don't comment on political matters. There is no law preventing the Queen or any royal from expressing their opinion on any matter. I always saw them in the role of a circuit breaker - that they would step in when England was imperilled and put their feet down. This did not happen.
(The royal family proved their worthlessness. I now see them as nothing but arrogant parasites - I should have all along. In a just society, they'd be stripped of all their stolen wealth and forced to make a living like the rest of us.)
The long-term consequences of the industrial revolution that Britain (prominently) birthed look like they will inevitably devastate our ecosystem. If Britain collapses first, it will be just desserts.
