The EU is threatening to impose a hard border.
The Republic is determined to remain in the EU and so will have to toe its line even though it will create hardship for Irish people on both sides of the border.

The quote I provided,
"Prime Minister Theresa May has said there should not be a hard border after Brexit, but Dublin's Foreign Affairs Minister Charlie Flanagan has voiced scepticism over the reassurances."
