However the facts were at the time there was a treaty, negotiated peacefully with their interests in mind that didn't require them to bend the knee. It was just players abusing their power by singling out players and actions they didn't like which they had no actual control over.
If you don't want to treat SS peacefully, then don't but you can't just pick and choose which players/actions you like and dislike and you certainly can't expect SS to universally adopt your laws/values. You can't make a treaty with the Seanchan and expect them to suddenly stop being Seanchan. Of course, they'll respect the laws as per the treaty in your nation but they're still going to be pursuing the Corenne elsewhere.
I also don't know that we necessarily are destroying anyone down south. So far we've lost two wars, we have a treaty with Mayene, peace with Tear (for the time being), and there are a couple of other nations wanting to make deals with us.
At the end of the day, you're all going to swear the Oaths eventually though.
