I'm pretty sure he's speaking metaphorically.
At least I think he's speaking metaphorically.
God, I hope he's speaking metaphorically.
The quote is via the Office of Poland's President, Andrzej Duda from his speech last week:
President's speech marking the central celebrations of the National Day of the Third of May
It's down toward the end of the oration, where he talks about getting the Commonwealth back together (kidding)
....I hope that for decades to come, and God willing, for centuries to come, Ukraine will be a brotherly state to the Republic of Poland, the country where – as I hope President Volodymyr Zelenski prophetically said – there will be no border between them and ourselves; that there will be no border; that we will live together on this soil, rebuilding and restoring our shared happiness and strength, something that will enable us to withstand every danger, and that will deter any attack or threat in the future.
I have no doubt that the enormous potential lies primarily in people – both in Poles and Ukrainians, as well as in our neighbours: Lithuanians, Latvians, Estonians. I firmly believe that we are capable of building here, in our part of Europe, a great community of nations – a strong community, as it should be, as our history has taught us.
Long live the nations of the former Commonwealth! May God protect them all and bring them happiness and prosperity! Long live Poland!
If the 'borderless' references are not metaphorical he risks this (please note, Polish flag is upside down, I did not draw it!):
I stole it. From The Fly, who appears to be quite the Russophile.
