Not informed on this particular instance but 90% of illegal immigration to western countries happens because the US, UK, France, or etc, fucked up the migrants' origin country one way or another. A perfect example of this is the US: most immigrants are from places fucked up by either the US overthrowing any left-wing Latin American government, or by awful US drug policy. Most nations not only have a moral responsibility to migrants as fellow humans, but they are usually directly responsible for those migrants wanting to leave their homelands to begin with.
