well.. it wouldn't make much sense to cause unrest in that region against the owner's realm if some foreigner loot it.
if nearby regions belonging to the foreign looters have significant followers, then unrest in those regions would make sense.
mass militia in the form of "angry faithful" may or may not hurt the region... i mean.. it's not like we haven't seen a region looted to hell to get partisan/etc which are then killed, etc to depopulate the region.
would be nice if say... out of a region of 8k pop, let's say 80% following, 2k rise up to fight the looters... whoever left alive out of the 2k then go back into the region's pop after the foreigners get booted out.
