p.s. The Brits are many things but stupid - on balance - they are not!
A few archeologists even discovered traces of an Empire, they once had. (... which Churchill managed to blow up with remarkable ease, ironically while trying "to preserve it". Good job!)
GB leaving the EU was the obvious as well as an existential step which soon no one will be able to deny! Simultaneously, Britain turning (almost exclusively as far as meaningful alliances go) to N. America is about the best placed bet under the circumstances.
... which is bound to happen to a country where history is taught and where the majority of the population is functionally literate. (The same could not be uniformly stated for the majority - and meaningfully fascist - EU, where the member states managed to go 0-2, every time they fielded their Dream Team. No wonder that, true to form, they are now clutch for 0-3!)
