Here is a story to help understand this strange complicity. Suppose there were two countries across the sea. There were an island in the sea. Both countries claimed the island as their territory. However, neither country occupied the island because they wanted to avoid a military conflict. However, sometimes both countries sent small landing parties to the island on different days and quickly withdrew from the island. The side that sent the landing party declared to the world each time that the island is our territory, while the other side deliberately stood by and declared to the world at the same time that their landing on the island is not an occupation, but only a drill. It's a strange game for the third party, but it is necessary to keep their maritime boundary in an undefined state so that permanent conflicts between the two sides can be cleverly adjusted in this way. この表現は自然ですか？

Here is a story to help understand this strange complicity (I don’t think “complicity” is the word you want here - I’d need to know more about you mean here to know for sure.)
