Or, looked at it another way - in the interests of the people in both Northern Ireland ........
You are entitled to your political opinion, but the hard facts say otherwise....
The NI Protocol and Windsor Framework are not in the best interests of Northern Ireland. The consent principle under the Good Friday Agreement and the balanced conditions that existed in 1998 have been totally undermined ...... hence the Unionist ( British) politicians ( largest designation under the GFA) in NI have refused to operate Strand 1 ( devolved government) that would result in implementation of foreign laws that are undemocratic (no say whatsoever by the NI people) and go against international human rights convention (territorial integrity and national sovereignty of states undermined).
Economically, the largest market for NI is GB by a HUGE margin. So trading across a border that breaches the UK Act of Union is unwise (read idiotic). Getting items from GB (UK internal market once governed by the AoU), is far more costly ....putting NI at massive disadvantage, compared to the other UK nations.
Moreover, when EU laws diverge from GB laws ( Brexit benefit) .... Then NI producers will be forced to abide by the EU rules ...... and further impact competitiveness and ability to trade with their largest customer base. Diversion of trade was supposed to be a key issue that would trigger the NI Protocol Article 16.....but has never been used, but should have been, according to the 'rules'.
There are a small number of low value industries that will continue to operate the same as when the UK was in the EU...... but that will not compensate for the GB trade impact and additional costs forced upon everyone in NI.
So, the NI Protocol and Windsor Framework is ideology only...... in reality it is economically damaging and does not have the consent of the largest designation of people under the GFA....... A complete recipe for long term harm.
Winter is coming.....
PS ...... The Common Travel Area existed way before the EU ..... and this allows travel across the UK and Ireland. ( The EU even tried at one point to ban it to inflict even more damage), even though it had nothing whatsoever to do with them.
PPS ....... Regarding meddling foreigners sticking their noses into UK affairs .... No other country in the world would accept being annexed into the EU as NI has been forced to. The US would not do it with California to Mexico....or England would not with Suffolk to the EU ....... Ukraine has not accepted it with Crimea either.
