I ~~could be wrong but I think the way foreign litany bases work is that they are in the thinnest legal sense "sovereign foreign territory." To which I mean, the activities conducted on these bases are outside the control of the country who's land they occupy.~~
Edit: I was wrong, amd the US are just tennants on the land which makes this a very questionable thing that they are doing.
Thank you for the correction! That makes what they're doing against the SOF rules/law, then?
