The UK wanted this. remember trade deals take time -- even the RENEGOTIATION of NAFTA / USMCA took a year.
The big problem was on the Irish border question, the agreement sets a backstop which will come into force, in the case that there is not new agreement between EU and UK before the end of the transition period. In that case, UK will remain in a customs union with the EU. Neither party can unilaterally withdraw from this customs union. The goal of this backstop agreement is to avoid a "hard" Irish border, where customs checks are necessary
But the irish border cannot be made hard as per the Good Friday agreement that the UK signed in 1997. the EU did not allow the UK to bully Ireland.
what more concessions are you looking for?
Theresa may wants to beg the EU to offer a concession on the Irish backstop. That's it -- what do you, FLT-Bird, want the EU to do with this? Allow the creation of a hard border in NI-RoI that violates the good Friday agreement? Or keep the border open and that will violate what people voted for in the 2016 referendum. What is your plan for this?
What would I urge? Hard Brexit. If the EU wants to erect a hard border in the Republic of Ireland - and pay for it - in the teeth of fierce opposition from the Irish who do not want that, and if they want to pay for manning that border, let em!
As a political reality, I dont think they can do it. I think theyre just posturing and that this is part of Project Fear 2.0. Hell, the EU cant even defend its borders from the millions of military age males pouring in from 3rd world shitholes in Africa and the Middle East......but theyre going to erect a hard border in Ireland and pay for its upkeep? Dont make me laugh.
