I live in the Netherlands. The closest one was about 260 km from where I live.
Of course, not any more.
I completely misunderstood the context of this discussion and revoke my mildly snarky comment. You are correct.
Was that on a country that went on a genocidal rampage just before and lost the war after killing millions all around Europe, which was decided to be divided in several parts, of which USSR got to control one, and which still developed into an independent country less than a decade later?
To be fair, if you stand in the middle of The Netherlands, 260km in any direction and you end up outside of the country. Which base are you talking about?
