OSC and IC affiliation clarification

[The Savage]

Let's say I am Kruger or IDF pirating around Omegas or Taus. And then, I come across OSC or IC player in said area(s).

Either ID allows me to pirate corporations that belong to house at war with Rheinland/Gallia - let's say Liberty-Rheinland Peace is not established into lore and ceasefire is not actual peace.

But then, we have IC and OSC - which according to their respective roleplay are no longer Liberty corporations, but Sirius-wide entities, in shape akin to GMG or IMG - having actually autonomous status as both OSC and IC are rather doing business outside their house and have bases outside their house of origin.
