So we shouldn't ever examine evidence for decisions in retrospect?
Right now, Brexit looks a total mess and not worth it - unless certain nebulous concepts like 'taking back control' and 'sovereignty' (though parliament itself has admitted that it has always been sovereign) are important to you.
Yes we can examine evidence if you'd like to do that.
I do agree that Brexit is a total mess (it doesn't look a total mess - it is one) It probably is worth it though because we have to go through all these discussions in order to make Brexit work. So they have to go to Brussels and talk about it a lot - we have to try to get to March 2019 in a sensible manner. Hopefully we can then achieve Brexit and everyone (or most of us) will be very happy .... (?)
