Would NATO interfere in what's essentially a domestic UK dispute? Could the USA invoke article 5 if Texas decide to secede? Would Spain have invoked article 5 if the Catalans had succeeded, or had gotten closer to it? In any case, would any of those NATO interferences be desired? I mean this by the local governments, but also by the rest of NATO and the world in general? Would there really be any political will inside of NATO to interfere?
