The war started in 2155 in canonSo I've seen some people saying we are at war with the Romulans, but we actually aren't yet.
It's still 2151 as of the latest turn and the war doesn't start until after 2155 at the earliest, we have time to work on some things.
The end of that retrospective is still in the future, like plenty were last thread.
It's possible that a more capable Enterprise actually forced the Romulans to accelerate their warp preparations, leading to an earlier war but one they're less prepared for
