"unauthorized" is a weird description. the iranian government is the sovereign regulator in iran, and prsumably they did authorize it. they dont need anyone else's authorization, same as nobody authorizes what happens in the US except the US government
I think it's reasonable to use "unauthorized" to include international law and treaties. It is true that the US (and maybe every country?) also does "unauthorized" things, by that definition. But I still think it is a reasonable word to use.
