"It is obvious to me the EU see the Irish border as the achilles heel for them to focus on. "
Then you miss the point entirely
The issue of the Border is vital to Ireland - both North and south
Until you/the UK grasp that particular nettle you will never understand the situation Britain is in
One of the most important aspects of keeping an open border is the fact that it is very much a part of the Peace Process and how the two halves of Ireland relate to each other
Suggesting that it is a political ploy is shortsighted beyond belief
