I think this is correct; Trump is the most consequential president since at least Nixon. Doesn’t mean that he’s done good (the opposite, really) but that there’s no undoing the magnitude of his changes. All the non-Trump presidents from Ford to Biden are historical footnotes https://www.notus.org/perspectives/trump-as-alexander-the-great-a-theory-that-explains-iran-and-everything-else
Although this part is wrong:
> We could even see the dollar lose its status as the main global reserve currency. Trump’s use of punitive tariffs and sanctions has already inspired key nations to discuss an alternative. If this were to happen, the United States could no longer run large budget deficits with impunity.
This blog explains why reserve status has nothing to do with deficits: https://theworkbench.jeffspross.com/p/is-providing-the-worlds-reserve-currency
