As I have said often, the Cold War is over. Global communist expansion has ended and atrophied to the point where only a few representative examples remain. Immigration policies that were designed to support cold war objectives are pointless in the modern world and should be scrapped.
The Cuban wet foot-dry foot policy is one of those. So are all of the asylum laws we currently have in the USA.
The basic rules for immigration to this country should be based on the USA gaining some benefit from allowing the immigrant. Anything that doesn’t fit this rule should not be allowed. Your homeland is over-run with sprinting zombies? Not my problem. Tribe next door goes on a killing rampage? I don’t care. Can’t buy food in your country? Sucks to be you. If the asylum seekers of the world need someplace to go, there are 198 other countries in the world to choose from. I suggest they try one of those that is culturally, linguistically, and religiously more aligned with the place they are fleeing from.
Where could the Cubans go? How about Havana? Or Haiti?
