Zoners - why they do exist?

[The Savage]

Now on the topic, Zoners are more or less the Switzerland of disco, (...)

The problem is, they aren't, because Zoners aren't the single faction. Anyway, if any other country found a single trace someone is allowing terrorists into one country, there, sanctions against it or even nuke the hell of that place.

Zoners aren't Junkers, who hide their bases in barely accessible places. I get it, Junkers are Junkers. But Zoners? They are right at the house trade routes, in easily accessible places - not only for traders, but also for a small assault group with unknown IFF.
