To expand on my referendum point. One of the reasons the UK is in the mess it is today is because the Tories promised to treat a non-binding referendum as an actual election.
They could have taken the result and seen that a significant minority of the british voters wanted to leave the EU, with a large undecided part as well. On that basis they could have set a party policy, looking at the actual economic costs, sorting trough which of the leave campaign's promises were empty (all money will go to NHS, the EU will give us everything we want in return for nothing) and which problems leave totally glossed over (like the NI border) and then made a comprehensive package with which they would go the EU and then call an election on that platform.
It would not have ignored the 'will of the people', but at the same time would have been an actual competent plan.
Now, they have nothing and the main proponents of the leave campaign have contributed nothing to the actual process either.
But who knows, maybe an uninformed 'it will all turn out all right and better than before' is an actual basis for international relations. Time will tell.
