Northern Ireland got the best deal of the three. Thanks to the Good Friday Agreement, people there can get Irish (and therefore EU) passports.
This is a perennial issue in Scottish politics, but Scotland, unlike Northern Ireland, and maybe Kent, does not have a land border with the EU.
My personal hope was that the UK would remain in the EU, but both the EU and UK would take a look at themselves. Instead both are heading more and more towards censorship and heavy control of their citizens.
