It is bcs they were fighting on behalf of UN forces
I agree with your thought that its an insult, tho
There will be a repatriation ceremony in Hawaii, I believe
Its some kind of ceremonial thing
They are basically just assuming they are Americans at this point
Gonna go thru detailed DNA match in Hawaii
The UN soldiers are the ones who examined and certified the remains and other items
UN soldiers at the DMZ then took control of the remains, held a prayer service, and put the UN flag on them
The US flag will be ceremoniously put on when they reach US
