Exterminating an entire people is hard, and you’re going to get more than a few people object out of sheer conscience alone. Stopping the reavers from stealing your wives and your crops, yeah, you’ll get people to support you. Taking the fight to the Iron Islands to punish them for a generation’s worth of thralldom of the green lands, sure, you’ll get plenty of buy-in. Killing everyone down to the youngest child? You won’t have people lining up to support that, even people with blood feuds. There’s a reason the Tarbeck-Reyne massacre was so infamous in Westeros was how excessive it was, and that was just two houses. Imagine an entire people. The war engine it would take, the atrocities you’d have to commit to sustain it, it’s beyond what I think Westeros is capable of, to say nothing of the ethical implications of such a practice.
The Armenians, the Jews, the Muslim Bosniaks, their survival is a testament to how difficult it is to kill off a people and a culture. The Ironborn are no different. Being born ironborn shouldn’t be a death sentence, and there’s plenty of examples of great ironborn men and women. Qhorwyn the Cunning, the three Harmunds, Quellon and Asha, Rodrik the Reader, all of these people promote an ideology that’s compatible with Westeros while still maintaining a proud and unique seafaring tradition.
Thanks for the question, Anon.
