This thread is becoming a Nationalist battle and is what EU wants. Weaken the Union and it is easier to control?
No deal not the best outcome, but looking likely as very difficult to juggle the WTO requirements, GFA and Brexit at the same time which happened in the following order;
WTO established 1 Jan 1995
Those who were EU members at that time are all WTO member.
GFA established 10 April 1998
The only current EU members who were not WTO members at this date are; Croatia, Estonia, Latvia and Lithuiania. So ROI, UK and the other major EU members agreed WTO before GFA was established.
Other major Countries who signed WTO before the GFA are; USA, Japan, India.
Brexit voted in 23 June 2016, but not yet happened
If UK leaves without a deal with EU, then UK will have to trade on WTO. Under WTO there is no requirement for border control. UK could simply allow goods to flow into UK without any checks or tariffs, but must apply the same principle to all other trading partners.
However, EU countries are entitled to impose tariffs and checks on goods imported from outside EU. So UK could sit back and wait to see what happens at the Irish border.
Checks or tariffs imposed by ROI/EU on NI would be out of UK control. So any comment about the GFA not being respected would be directed at ROI and EU in general as opposed to UK.
Is this Johnson's strategy behind no deal?
