UK and Spain's history is very similar. Both had big empires, they lose them, now are middle powers.
The advantage we have in Spain is it happened to us a century or two before, and we fell even lower.
It takes time to acknowledge the fact you are not a superpower anymore. Brexit made very clear the UK are still digesting the fact.
Since we are poised to have China and probably India as the next two main powers, as Trump is making sure the US drops out, let's hope Russians and the US take it easy. It doesn't look likely, seeing what they are doing now. Well, one can dream...

Yes good point about us both following a road trod by Spain & not realising it....
