worked out fairly well in the first and second world wars, and for south korea, most of central america, eastern europe in the cold war.
not always admittedly.
more wins than losses though.
I will concede you World War 2.
I won't. World war II, which was a massive joint effort that was already 4 years underway when the US came to the party ("FASHionably late, dahling...") & was by no means about "freedom" as much as it was Boon & Otter saying "HE can't do that to our pledge..!" "Right, only WE can do that to our pledge!" Saving folks from subjugation? Right. And how WERE things afterwards for Jews? Oh, still kinda shitty? Well, the Slavs were OK, right? ...Handed over to the Commies, huh? Hm. How about the Romani? ...Deporatation programs & "Go home dirty Gypsy" even today? Really? Well...we freed the Jehovah's Witnesses & the Catholics at least!
Fuck, that's just the ETO. Seventy years on, there's big chunks of East Asia that love taking Japanese money & turning around to shit on their bed. At least when the Chinese invaded their territories in the past, they didn't try to work & rape them out of existence.
