I live there. Peace is pretty stable. The political elements you talk about is mostly politicians posturing with weak hands that they dealt themselves.
Most people are pretty damn happy that we're in a situation where business will be able to export to the UK and all of it's future trading partners AND the EU with all of its future partners without much friction.
Granted, it hasn't all been smooth sailing, but the next election cycle here should provide a lot of clarity as to whether or not the place can become a great base to trade from.
I know, the problem is if you are a business from outside this island you are going to be spooked by all that nonsense
Why would anyone setup shop in NI if they have no certainty that NI's unique access to UK and EU markets wont be shredded up by numpties who still think its the 17th century
