You seem to be suggesting that Britain should abandon its representational democracy.
That takes thread drift to new, stratospheric levels.
If that is not what you mean, stop being a twat and tell us how you envision Britain "having a say."
My position is clear. The people of NI should make the decision.
Not the Republic, though they agree with me anyway.
And not Britain. The British do want rid of NI, but if asked I am certain I would be found to be typical in wanting NI to decide about NI.
As with Falklanders and Gibraltarians.
There was negligable support for troops out even at the height of the Troubles.

And now your big question!
"If you are going to leave the situation as it is WHAT IS YOUR SOLUTION TO THE PRESENT AND MOUNTING VIOLENCE AND UNREST? "

The violence of the Troubles is over.
PSNI are dealing adequately with dissident Republicans. The army is not wanted or needed.
Sectarian tension is a fact of life. We have it in Glasgow too.
Changing the border would not make it better and probably make it worse.
You invite personal abuse because you never let on what you actually mean or want.
This sterile debate should have been wound up days ago.
