@MysteryTripAgain - Even if a WTO border was not installed in NI, Ireland would still be required to install an EU border.
I assume you have being following the discussions between Ireland and EU 26 wrt to this? The agreement is that Ireland will do what they can and take things as they come, with regular reviews to see what needs to be done. That is not an instant border.
In contrast, the UK must treat Ireland the same way they treat every other member of WTO. Therefore, if they create a wishy washy border with Ireland, they must do the same for everyone else. Taking back control of your borders?
GFA becomes void under the Vienna Convention. Not going to regurgitate the posts here, but look on the thread "Johnson has 30 days to make a deal" to see the legal position on the connection, or lack thereof, between;
No it does not. As I have repeatedly said, there's a massive difference between circumstances that make it impossible to comply with a treaty and deliberately taking actions that contravene the treaty. With its red lines, the UK is deliberately taking action that contravenes the GFA.
Subjective question. Those effected by acts of violence will likely say no. Those who are not might say yes
Again, you are avoiding a direct question put by @bellinisurge. Let me ask it as well: Do you personally believe a return to violence in NI and, quite likely GB, is a price worth paying for brexit?
If your answer is no: Do you personally believe a return to violence in NI only is a price worth paying for brexit?
