All of your questions are valid. Visiting NoKo is not a normal thing. I thought of Otto as soon as I heard NZ shooter traveled there. Maybe MK ultra training ground? Also, both Tarrant and Otto look similar. Maybe Otto didn’t die? His death was suspicious as fuck and there was no autopsy. Why?
If they are cloning in NoKo, maybe they sent back the Otto clone and that’s why it died so fast upon return. It would also explain why KJU said, he knew nothing about what happened and why POTUS said he believed him.
