Be a colonizing country;
Make money by exploiting free human resources;
Get rich;
Slavery is abolished;
Some of the ex-slaves who served for the colonizing countries migrate to their "masters";
Be arrogant and ignorant enough not to integrate them;
Keep bombing their home countries for $$$;
Complain about them not wanting to integrate, rioting and/or comitting terrorist acts in support of their countries of origin, culture and religion.
Not to mention disconsidering people dying in Middle East, just because "there are dying people every day there, so it's not important". You could drop nuclear bombs there tomorrow and the majority of the Western civilized citizens wouldn't give a damn.
Also, France stating that they are at war with ISIS? Aren't they at war with them since they bombed them the first time? What was their relationship until now? Pact of non-aggression? Trade? This is very dangerous nowadays, you can bomb someone without being at war with him... Interesting.
