Gosh, if only Trump were an authoritarian xenophobe, so many lives would have been spared.
He IS an authoritarian xenophobe. But if he was a smart authoritarian xenophobe, or at any rate smart enough to overcome his breathtakingly epic narcissism, the US response could have been very very good instead of very very bad. We'd be marveling (or lamenting, if Democrats) how the pandemic played right into his hands.
Nothing in my alternate history is really outside the purview of what Trump could do. He's got few ideological keystones and no particular need for consistency anyway.
