There are many controversed views about the latest mass migrations as a consequence of wars, oppression, genocide, religious fanatism, corruption, economical and ecological disasters, not to forget overpopulation, extreme poverty, violence and abuse.
On the one hand, hundreds of thousand desperate migrants are flooding Europe, and many risk their lives to escape war, violence and slavery. But they come in too large numbers; no country can deal properly with them, and mass processing is fraught with fails, abuses and blunders.

No one can turn a blind eye on such tragedies, but neither can already deeply split host countries neglect large parts of their own populations, namely women and children, and let old and new conflicts and violences from all the sides escalate ...
