This seems like a reasonably good analysis, but Trump's frequent campaign promise to deport all the "illegal immigrants" seems like it might deserve a prominent mention, even if only to explain why you don't think it will happen. During the campaign, Trump often defined "illegal immigrants" as 20 million people or more, some of whom have US residency visas that Trump thinks they shouldn't have gotten and therefore aren't "illegal" in the conventional sense.

If it does happen, it will be the largest "ethnic cleansing" in human history—bigger than the Yugoslavian migrations, bigger than the Armenian genocide, bigger than the Holocaust, bigger than the Holodomor, bigger than the US's previous forced removals of Native Americans. I say "ethnic" because it's primarily directed at people who are dark-skinned because of their Native American ancestry and driven by racism against them. It isn't directed against white illegal immigrants like Elon Musk and Melania Trump were.
