In the prime timeline, during that same general periord, the Federation was also at war with the Talarians, the Tzenkethi and the Cardassians. It's not unreasonable to assume that that was also the case in the YE timeline. That's four fronts.
Indeed, with the Klingons keeping Starfleet busy, the other three comparatively minor powers may have been even more aggressive. Perhaps they were even working together. And maybe others joined the pile on, too: Tholians and Ferengi, for instance. Not to mention twenty year's worth of worlds that joined the UFP in the prime timeline deciding to maybe hold off a bit in the YE one, lest they pick a losing side.
Maybe not. Who knows. But it's not JUST the Klingons. With four fronts to worry about (admittedly perhaps not all at the same time) and a Neutral Zone to watch, the Federation has still been able to hang on for twenty years.
Not bad, really.
