One day there will be a massive wave of climate refugees rushing out of the uninhabitable zone and there will be US soldiers in the border guard towers with flamethrowers. The US will welcome immigrants when it suits them and roast them when it doesn’t.
As I am in Berlin right now I’ll remind us it wouldn’t be the first time people on top of a wall had kill on sight orders.
Are you talking about Canada?
Whether all this was in some sense worth it for mysterious realpolitik greater-good reasons—I dunno. Looks pretty bad on its own, anyway. Not enough help to win—but just enough to keep the fight going forever. Doesn't make much sense to me unless the point was to accomplish exactly that (to disrupt Russian and/or Iranian interests in the area without pushing too hard? To keep Syria too distracted to mess with Israel? Destabilize Syria so it can't interfere with Iraq's fledgeling state? I have no idea what the real motivation is or was, but it sure as hell doesn't seem to have been "help the Syrian people"—if it was, we've screwed that up pretty badly)

I was mostly thinking of Syria and Daesh, and had forgotten about Libya. A non-insignificant chunk of refugees headed to Europe transit through Libya - which didn't use to be the case before Gaddafi was deposed.
The US went for Syria/Assad leading the intervention and whilst France picked up it's involvement against ISIL & the like particularly after the Paris attacks it wasn't as big on it as Libya.

Also, the US was bombing a couple of Middle Eastern countries then: creating the said refugees who could reach Europe on foot and/or boat, but not the American mainland .
