I bet! No offense but the you from my universe is super old. So yeah, couple decades gone by. You know of the war, the plague, the other attempted war? I'm guessing there wasn't any sort of established peace yet in your time. But it happened.
There was sort of a "you stay in your lane I stay in mine" period which went...as you would expect. They also had their own internal stuff to deal with in the meantime, obviously. Then another Federation/Klingon war in the 70s, this time involving Cardassians, Changelings and the Dominion. Then we united against the Dominion, aaand alliance reestablished. Nowadays sometimes we clash, most of the time we're allies. They still hate the Romulans though.
