In the Canukah "Al Hanisim", it says: "You delivered the mighty into the hands of the weak, the many into the hands of the few, the impure into the hands of the pure, the wicked into the hands of the righteous, and the wanton sinners into the hands of those who occupy themselves with Your Torah."
But the Romans helped the Jews? As the Gemara Avodah Zara 8b says:
דכי אתא רב דימי אמר תלתין ותרין קרבי עבדו רומאי בהדי יונאי ולא יכלו להו עד דשתפינהו לישראל בהדייהו והכי אתנו בהדייהו אי מינן מלכי מנייכו הפרכי אי מנייכו מלכי מינן הפרכי
The Gemara elaborates: As when Rav Dimi came from Eretz Yisrael he said: The Romans waged thirty-two battles with the Greeks but were unable to defeat them, until they formed a partnership with the Jewish people and finally vanquished the Greeks. And this is the condition that they stipulated with the Jewish people: If the kings come from among us, the governors [hiparkhei] will come from among you; and if the kings come from among you, the governors will come from among us.
So while the Gemara implies that the Romans wouldn't have been victorious on their own, they definitely helped the Jews.
So do we say that Hashem gave "the many into the hands of the few" when it wasn't just Us vs. the Greeks but Us + Rome vs. the Greeks.
