The Anglo-Irish Peace Treaty of 1921 was negotiated between an illegitimate/unrecognized state and the British government. Given such, it's intrinsically invalid, as an entity cannot negotiate on behalf of itself if it doesn't exist, and treaties can't be made with it as there's no partner to sign the treaty with. As such, the whole of Ireland is still part of the UK, but the majority of it is occupied by EU forces. As part of peace negotiations, the EU and the UK should negotiate reasonable boundaries, such that Ireland, Scotland, and Greater London remain part of the EU, and the rest can form a rump UK Independent State. Makes as much sense as May's deal.
