Here in the UK we are going through the final convulsions of Brexit (British exit from European Union). It's divided us and it will take years for the wounds to heal.
However, ever the light hearted nationalist* that I am, what neighbouring or rival county, state, region or nation do you feel you could both live with and without?
For me it's England and the USA. As a Scot, I was brought up as a default nationalist, taught to resent England and all that she imposed upon us. What I have since learnt is that there is little difference between us and that all the inequity is borne out of population size and political power; nothing to do with the relative nature of either population. This explains why they beat us at sport (mostly) and boss the UK parliament.
Extrapolating this further we have the UK and USA. Having overcome my England anxiety ( I've lived there for 18 yrs and love it), I become a 'Britisher' my attention turns to our badass cousin, USA. How hilarious and rediculous I feel that this nation makes me feel so small and yet reassured in equal measure. Some days it feels like a takeover and others a reassuring thumbs up from a good friend and neighbour.
What I take from this is that there is no good reason to have a fixed opinion on anything and certainly no reasonable purpose for nationalism; not even if football is called soccer and they drive on the wrong side of the road. ?
Love and peace. ?

*not really a nationalist, just frustrated that Scotland will never win the World Cup. ?
