This seems more like a move designed to frighten China -- or force them to spend money making LLMs -- then an actual threat. The clues are that Trump ceremonially blessed the deal but did not promise money (SoftBank et al will, supposedly), and then Musk said that's all fake because SoftBank doesn't have the money, and Altman countered that Musk should not be butthurt and should put America first. Who does that? I'm thinking, no one who has something real on his hands.
