The reality is it won't be dealt with, because the power structure of NI is really an illusion.
The real risk of returning to full blown sectarian carnage means its always a tipping scale and the deep seated hate in some fractions of society is allowed to countinue generation after generation because really trying to stamp it out will just lead to a new generation of disillusioned, "fighting" for a cause they actually dont understand. And their wants still take priority over the vast majority of people who just want to get the fck on with living a half decent life.
Like the retrotric of immigration taking jobs, houses, services bringing violence unchecked. Yet the same people are so uneducated they dont realise the problems in the north weren't created, nor countinued by immigration.
The problem is they have a completely ineffective "government" structure still underpinned by hate rather than genuine care for building a society that actually works under years of British government's who didnt really give two shits about what is happening in NI once they stopped bringing those problems across the water by way of hidden bombs in bins.
