Once you get past the noise from the RW press in England. Plus the gaslighting from #Sunak & unfortunately named new English Home Secretary, if they pull out of it, yes they threaten the Good Friday Agreement (which I don't think would bother them!)
BUT what might bother them is the Trade & Cooperation Agreement with #EU which is underpinned by #ECHR. Also their newly announced membership of #Horizon.
So are they really going to withdraw from it??
Stop being distracted by the noise...
