For 17,196 days, we had the full might of the EU's experienced negotiating team on our side.
Nobody in our government has ever known any other way. So they are utterly unprepared for an adversarial relationship.
They are simply treating us as exactly what we became on 31 January: a third country, outside the EU family of member nations.
Some regrets, absolutely. But little sentimentality. Just pragmatism.
Fail to grasp it, and you are guaranteed disaster.
