I made me a script to load country data from Wikidata. And what do I see in the output? Weird numbers linked to the Sovereign Military Order of Malta. It has zero land, two citizens but 13500 order members, 80000 volunteers, 42000 employees. And it has diplomatic relations with 108 countries—which, according to analysis by experts in whatever field this is, exhibit the signs that the order is indeed a de-facto recognized sovereign entity even though this recognition is not so firm as that of a full-blown state.
BTW, if we consider just the members and volunteers, the order would rank twelfth least-populous country, between Andorra and Antigua-and-Barbuda. And its population would be almost 1/5th that of the current population of Malta.
However, if the territory dispute breaks out, Hanwha may have to fight it out with Hyundai's tanks and artillery. Notably, the same Hyundai's division also produces most of South Korea's train cars and locomotives.
