Care to answer the original OP Mysterytripagain? What would you compromise on?
First of all you need to remember that a negotiation takes place between TWO PARTIES. Therefore BOTH PARTIES NEED TO COMPROMISE to avoid a no deal exit by UK from the EU.
EU have stated that WA signed by T May (illegally in contradiction of the Miller Case Law) can't be revisited. So it is correct to say they are making no compromises since Johnson took over.
However, DUPers and ERGers have said they will not accept the WA.
DUP argue that WA contradicts the GFA as it changes NI status from UK . ERG want no deal anyway.
If enough labour MP's change their mind the WA might get through parliament. If not then there are the following possibilities;
The Benn Act is amended to extend beyond Jan 2020 and EU agrees. So remain supporters might think they are getting remain through the back door, but not correct. For as long as there is uncertainty, sterling will be weak and some employers may leave the UK based on uncertainty. Service sector is particularly precarious as very easy to relocate. Other than; office space, computers and telecoms what else is needed?
UK leaves with no deal and labour MP's are held accountable for thwarting the WA for times consecutively in the past.
So it is about EU and Ireland deciding what they want to protect most. The EU laws or the GFA and decide accordingly.
An open border sticks 2 up to EU laws, but protects the GFA and vice versa.
UK does not have that dilemma. WTO does not require a hard border and UK can sit back and wait for the EU to make the first move.
NI would become a prime target for suppliers of dodgy products in the knowledge there is an easy path into Ireland the rest of the EU. Anything that did not meet EU standards that originated in Ireland and resulted in disease in EU would be to Ireland's account.
Suggestion of NI only backstop and special economic zone would get backlash from DUP, ERG and Scotland. However, most dangerous of all is the demand from other Countries who border Eastern Europe for the same special treatment. May even end up with wars in Eastern Europe?
