I had a great highly enjoyable childhood mainly because everybody I knew did a brilliant job convincing me that the world was a fun, happy, loving place (even if I was too young to know otherwise).
Nothing in my life involved war and destruction, fleeing my home with nothing but the clothes on my back, having to put my life in the criminal gangs who might get me to Blighty or let me drown (depending on whatever made the most profit). I can not imagine the ordeal of these children who deserve better (as all children should), and I would think that reaching dry land, you would finally be safe.
Yet this scum thinks otherwise.
Build him a time machine and send him back to live in Nazi Germany. The only place for him.
