Brexit

[Dave_Mole]

It is possible to have no physical border in Irish Sea or infrastructure at the border.

it's also possible for unicorns to graze in that location.

Technology can cope with most of this

and yet no technical "fix" has been suggested, because currently, no technology can deal with this. Specifically no current technology can deal with this at the border between NI and the Republic.

absolute contempt for sovereignty or democracy, as proven by the eternal backstop

wrong and wrong.

Boris could have forced EU to back down on that too.

Boris agreed it. It was the UKs responsibility to come up with solutions to the "border" issue. This was the UKs solution.

If Barnier wants a border he can put it between Ireland and France

then what happens between NI and the Republic? He could put a border between the Republic and the Moon, but it wouldn't solve the issue.

why does Ireland consider it reasonable for a border from ni to uk

because that's where the border between the EU and the not-EU physically is. I think you'll find the Republic are quite keen not to have a border. You might also like to have a little look at the Good Friday Agreement.

they can have one too between them and france

The Republic and France are part of the EU.

You need to capitalise proper nouns.
