I just saw a video a couple of days ago about one of those children who was adopted by an American family sometime in the 70s. The family gave him up to foster care within 6 years like he was a toy that you could just throw away when you don’t want it anymore. The worst part is they didn’t file his paperwork correctly so he was never naturalized. When he tried to correct it as an adult, he was deported instead because the background check that was triggered found a previous conviction as a teen (broke into his abusive 3rd foster family’s house to get his things). He couldn’t assimilate back in Korea and ended up moving to Mexico because the culture was more familiar.
It’s crazy how an incredibly huge tsunami was sloshing around for 9 days and no one was able to trace and find it fast enough to capture any video.
