Maybe I'll answer the issue of the separation from parents.
We have very ancient knowledge about separation from parents to protect children from war. It began with the London bombing in the Second World War, with children being evacuated from London and separated from their parents doing far worse than those who stayed with their parents during the bombing of London.
Recently a study in Finland has shown that people who were evacuated 60 years ago to protect them and separated from their parents still have more problems than their peers who stayed with their parents during the war.
It does not mean that war is good for children. It means that parental separation can have worse effects, and they are very long-lasting effects, which may lead to depression, but with functional problems. We're speaking of chronic depression and anxiety, which has a high cost in terms of the daily productivity of these people.
