The UK would have had to breach or at least seriously jeopardize the GFA to do so. An agreement they willingly signed up to. The UK brought that upon themselves.
Brexit doesn't, but the GFA was only possible because of the seamless border between the two countries. That lack-of-a-border can only exist if NI remains in the customs union. The rUK can only have a seamless border with NI if it's either in the customs union, or neither are. The UK decided the rUK didn't want to be in it. So now there's a border in the Irish sea.

Recognizing that putting in jeopardy an international agreement that brought an end to the troubles might incite violence, is not the same thing as threatening violence. It's common sense.

You're right, they were an ethno-nationalist conflict, during which the British government sanctioned the murder of its own citizens, and now continues to protect those murderers from prosecution.

Brexit in no way breaches the GFA. Threatening a return to violence in Ireland over Brexit is what I mean by "making things difficult".
The Troubles were not about sausage shipments between Belfast and Dublin.
