Oh, I agree that managing trade across the border is achievable. But as we discussed, that's only half of the problem. Freedom of movement is a UK red line. If we don't have a hard border between Ireland and N. Ireland then we have an open border for people. I'm not sure how we could overcome that.
The UK can't stop, or won't stop, freedom of movement of people on the Irish border because of the 1921 Common Travel Area agreement. Both the British Government and the Irish government have already acknowledged the longstanding agreement for FOM across the border. The only issue without an agreement is trade, and the UK has consistently said it wants to move to electronic monitoring.
Its the EU and Ireland that has continued to muddy the waters. Hell, Barnier himself said that it was doable late last year then rowed back on it and hasn't mentioned it since.
And a repetitive as it is, if there are electronic solutions already in use elsewhere in the EU why aren't they applicable to the Ni/Ireland border? Just what are the differences between the Norway/Sweden border, the France/Swiss border, the Estonia/Russian border, the Turkish/Bulgarian border and that of NI/Ireland?
The proposal from the UK for the NI/Ireland border is all checks are done electronically, and no check points. The EU isn't willing to accept no check points, unless the Backstop is adopted, and the GFA says no check points. So who is saying no, and is it a reasonable no?
