The Galaxy Class starship has a tendency to explode, versus the Constitution Class which could take pounding for hours without ever having a core breach. Perhaps because, in addition to the core being unsecured and normally unshielded, officers readily plug completely unknown USB devices directly into the core? Worse(?), the device obviously has a geometric axis, yet they have no problem pointing it at/away from the core.
Imagine the difficulty that the young Klingons will have trying to adapt to Klingon culture, knowing almost nothing about it. They won't have Worf around to gently guide them through the basics. From what we've seen of Klingon society, it's dog-eat-dog, and they are all completely unprepared for it. It's also not going to help that they won't be able to explain where they came from or who their family is, especially in a culture so obsessed with lineage.
Tokath is adamant that he has done the impossible in creating peace between Klingons and Romulans. The thing is, his "peace" is a lie the whole way through - the Klingons who came from Khitomer have accepted that they are living dead for having been captured and failing to kill themselves. And as for the children, everything they know about the world beyond their world are at best exaggerations and at worst outright lies, and they know little of their actual heritage and culture. Compare this to the residential schools where white people took the children of indigenous peoples' and made them conform to their own beliefs, disconnecting them from theirs. And this is what Tokath calls "peace" between the two races, by demanding that one not BE who they are. At that point, the fact that the children have no context of a world beyond the prison that they have no reason to question is just icing. Tokath's peace is a lie, and his own pride and arrogance blinds him to that.
