It's as a European that I say Europeans have to get over internal differences and stop thinking European countries are equivalent to the big players in the world.
The UK thought it was super special and better than the rest, and it got exactly what it deserves. We Europeans are probably better off forgetting the "geopolitical clout of Poland" and considering it embedded in that of Europe as a whole. It's no coincidence that Europe's enemies fan the flames of nationalism in European countries.
