Wow! A lot to absorb here. On the ID front, I like option 1. True that we have had some positive diplomacy with Kusari people but as we all know how Kusari treats Junkers, a few Kusari peoples that choose to accept us can always visit and perhaps in time with RP the Kusari government can judge us separately from Junkers as a whole.
As mentioned, Tinkers has much to do with humanitarian efforts and that is often recognized as an honorable cause by many. Not all but many.
I'll read some more and give further comment later.
