It always was going to be a hard choice anyway, China can threaten the homeland. If this is really a major shift(which I think it might be given Canadian-US stuff, seems like buildup to downgraded relations), US just made the choice far easier. It really is amazing, how it behaved over last few years. Hamstrung the fighter project by refusing to provide a single engine for years after signing contract for one lol, however much they bribed our generals all gone to waste by proving they can't be trusted right out of the gate. is going to be major winner from that probably.
