It should be case closed; EU one side, UK another; EU pays for the border because the UK doesn't want a border and for all intents and purposes, will be an EU border for their single market. Northern Ireland's a part of the UK, Republic of Ireland's in the EU; so why make the border down the Irish Sea cutting off NI from GB down the UK? We should take the EU to court and sue them so at least the EU pays a certain amount of billions to the UK for cutting the UK up. Didn't anybody stop and think about the British? That's why I'm all for the EU putting a border on the island of Ireland paid for by the EU since it's their border. People who think there cannot be Brexit without a border could be right for all I care, but the days of no Brexit are over, so this could mean the days of no border are over too. UK leaving the EU has created the need for an external border. I mean, I get it; the DUP's position was devalued since the December 2019 election so it's been made easier to do a u-turn on the promise to treat NI like the rest of the UK, but why must DUP suffer for Ireland's need?
