One curiosity, given the violence we have delivered on their heads, is why they then want to come here. Come here now that is rather than come before we bombed them.
"Them" is not one homogeneous group. Quite probably they have had violence visited upon them by people at home perhaps more than "we" flatter ourselves to have delivered. They have seen the films and TV of safe Europe and want to escape their instability. Put yourself in their position instead - surely you don't want to hang around and get co-opted into or knocked off by militias? Presumably lawlessness also creates opportunities for traffickers. Perhaps they have often imagined going, as you might imagine living in the South of France, but now they have finally got the motivation they need to take the risk.
