Yes, I know why the war was fought, but wars typically need two sides fighting each other. Can the Clone War really be called a war if there was one guy controlling both sides, though? To us, the audience, we know about Palpatine's manipulations on both sides and what the outcome was going to be either way, making a lot of heroic sacrifices pointless and even more tragic.
That's what I was getting at. It's not really "dumb" at all, it's just that if you were to look at it as a conflict like the Galactic Civil War or the First Order conflict, there's a big difference between them, in that the Clone Wars weren't really a conflict at all, more just a fancy charade. It's one of the most interesting aspects about the Prequel era.
