Heads-up warning to occupiers: you will never feel safe in Mariupol if you stay there . That child and many others will come back again and again , their own children too...
See Israel, it lasted over 19 centuries, until they came back. See Palestinians, they still try to get back to their land and fight for it, israel isn't safe and won't be for eons.
Do you want your children and their own children to live in fear.
Don't stay there, it's only going to cost all of you more. Leave before you get acclimated to those territories. Before a Russian child calls this foreign land his.
