Eventually, though, they'll have to actually live in the countries they reside in as, one has to assume, permanent residents. I helped sponsor my interpreter's visa years ago when I finished my time as an infantry platoon leader in Afghanistan. He landed in [undisclosed location] and has a stable job driving for a trucking company. He hates it here. He wants to go back. Do you want to know why? Because we let our girls go to school, because there aren't enough Muslims around him, and because he misses his home country, warts and all. He left because he was afraid that the Taliban would kill him, and he was probably right. He's probably still right. We rarely talk anymore, which is sad, but that's the reality. There's a wide range of views that interpreters held, and to be sure mine is absolutely not meant to be a representation of everyone coming from there.
I don't really have a point other than to say that resettling refugees isn't as simple as "oh just give them a place to sleep and some cash and the rest will take care of itself", like it's via osmosis or something that they inculcate the values and culture of the new "home" they find themselves in. This isn't software you can install, it's much harder than that.
