Re: USA and UK surviving into the Trek era
The implication is pretty clear, that nearly all of the countries today still exist, with their current names intact and a certain individuality.
The borders exist out of nostalgia and probably aren't remotely enforced or given much thought.
I think it's pretty much this.
Nations have been pretty much reduced to local townships, IMO.
