It is time for a #RegionsOfEurope 2.0:
The present-day territories of the traditional #Saxon, #Celtic, and #Scottish kingdoms of old could all #Rejoin the #EuropeanUnion, like the trendsetters of #EasternEurope. ;)
Sort of like simultaneously moving the #HadriansWall to enclose all of the #BritishIsles while concurrently eliminating it.
This would also make any #Ulster and #Scottish questions obsolete.
