"... it hasn't happened in Ireland and England yet, has it." For most people, yes it has. Even in the few years since the bombing campaigns stopped, in England the spasm of anti-Irishry that built up during Troubles has mostly dissipated. And there's never been much any real hostility towards the English in general in Ireland.

A generation of peace, and no squabbling over territory, and historical antagoinisms will just fade away.
