Was there a reasonable expectation at the time that the leading voices negotiating Brexit wouldn't have such a daft perspective?
I think it was a reasonable expectation that the leader appointed to oversee the UK Leaving the EU would:
(a) believe that the UK should Leave the EU,
(b) understand that the vote was a vote to end, not to renegotiate, a very complex arrangement; and
(c) use the two years to prepare the UK.
I am coming to the conclusion that Theresa May obtained her position by fraud because it is difficult
to believe that she believed that the people wanted what she is trying for, i.e. a Brexit in Name only.
Did you consider that before voting?
The referendum voting was a tick Leave or Remain, not select a negotiating strategy.
Most of us expected that David Cameron would stay and invoke
Article 50 (as he had promised) and/or handover to Boris Johnson.
Has anyone actually ever tried an unenforced border? My googling just finds Brexiteer proposals and US-Mexico border asshattery.
It also sounds a bit of an improbable situation to maintain itself. Immigration reduction is a major issue for the remaining ideological brexiteers, so to hear such people propose to just not enforce a border sounds very insincere.
I am puzzled as to why you should consider an unenforced border improbable
bearing in mind that it (a) currently exists (b) is specified in the Good Friday
Agreement (c) is what the Irish and the UK government say they wish to continue.
