In my opinion, mass immigration is a symptom. We’re not going to solve the problem by treating the symptoms. The better long-term plan would be to build a coalition among their home and neighboring countries to try and help them figure out how to address the stability issues at home. That’s way easier said than done, and it may not even be possible, but I just don’t see the current situation as being sustainable for decades on end.
That being said, for the interim, we desperately need some major reforms with how we handle asylum seekers and immigrants in general. I don’t have enough expertise on the matter to suggest how to go about that, I just know that the current system isn’t working well at all and is actively killing people.
