Without the USA the balance of power would shift indeed. Depends which way you wanna go but Russian or Chinese threat would probably be most believable for readers. I would start with studying history. There is no need to reinvent the wheel so to say. To paraphrase A. Einstein, the secret to creativity is to hide sources.

edit: if you wanna go really wild, something like United Arabs would also probably resonate ;) Or perhaps even wilder United Africans but for that, the novel would need elements of sci-fi.
