The conversation with Uncle Sam will be something like:
You aren't going to close your military bases, are you? Well, yes.
You aren't going to close the borders and enact border checks, are you? Well, yes.
You aren't going to require visas for Texan patriots to visit the US, are you? Quite possibly.
You aren't going to end all of those transfer payments you make? Hell yes.
What about the Social Security owed to our residents? Interesting question, isn't it.
There aren't going to be tariffs between our nations, are there? Everything is negotiable.
My child just married an American. Will he be able to live in the US? That's complicated...
