i mean they did very recently consider switching to the US dollar, which means at least at a government standpoint, they trust the US economy over their own at that moment. They used to hate the US in the early 2000's but its more 50/50 i think nowadays.
id imagine a certain generation hates the US mainly because of the US stance during the Falkland Wars, as its one of the major times where the US didn't enforce the monroe doctrine(when it typically would have). Of course as time gets farther from that time period that view kinda starts to mull off, sorta like younger generations in mainland asia's opinion of japan.
