I mean in the regular timeline, the Federation was losing against the Dominion, and they still found a way to win.
And in the alt timeline from Yesterday's Enterprise, even though they said that the Federation was losing against the Klingons and that the Klingons would win the war in six months, do you think that somehow, some way, the Federation would find a way to win?
Yes. The Federation found a way to “win” by sending the Enterprise-C back in time to Narendra III and preventing the war from ever happening.
