[LotR] Considering Eru Ilúvatar is helping the realm of Men destroy the one ring, why doesn't he simply just go down and destroy Sauron and his armies himself?

Title says all. I know it can't be that he fears Sauron, cause he's so much more powerful than the dark lord, so what could it be?

I don't think it's accurate to describe it as Eru "Helping the realm of Men destroy the one ring."

Rather the entire saga is the interplay of Eru's themes with those of his children. Sauron's downfall was foretold by that music, long before the creation of the world. In a sense, Sauron was destroyed before he was even "born."
