This is one of those things that sounds really nice in theory but in reality may be very dangerous. NK has routinely punished the remaining families of escapees. Im not 100% sure Identifying and seeking out the remaining families of our citizens is a good choice. For their safety or the safety of their families. Assuming they are still alive at all. A oppressive dictatorship with a statistically high chance of retaliation against the families of escapees... surely you can see how badly this can go. You’re just creating deadly hostage situations by identifying them. I just can’t say this is a good idea no matter how sad a painful it must be for them. The danger to the families in North Korea is so high.
