Brexit was promised to reduce immigration. Woops.
Maybe one day this country will be ready to admit it was a stupid idea
I think everyone who supported it has to die first.
To wit:
People still defend the Iraq war
Nobody defends the invasion of Suez.
There are plenty who supported the Iraq war at the time who now pretend they did not. Its a bit old now but this survey was pretty enlightening at the time as it showed people not just changing their mind but also outright pretending they never supported it in the first place: https://www.independent.co.uk/news/uk/politics/surveys-reveal-how-we-remember-not-supporting-war-in-iraq-but-at-the-time-we-did-support-it-a37171.html
Brexit will be no different, it will still have a minority of true believers.
