I always thought the "Clone Wars" thing in the prequels was a huge miss. I'm pretty sure the mention in Ep. 4 was just a throw-away line: "You served my father during the Clone Wars." Sounds cool and mysterious, and in a few words implies a vast history.
But here's the thing. The clones fought on the side of the Republic/pre-Empire. From the name, you'd expect the clones to be the enemies. It just feels off for the winners to refer to the war by their own troops, rather than the droids fighting for the enemy. Particularly that apparently the wars led to such distrust towards droids that they're regularly banned from cantinas.
And "Attack of the Clones"? When they attack, they're on the side of the heroes!
