Actually, it's more likely that Cocoon did. While it was never actually proven who started did, it was mentioned that all of Pulse's machines were built for defencive fights on land, as oppossed to those of cocoon, which were built for seemingly offensive aerial tactics.

True that! However keep in mind that citizens of Cocoon think, or know, that Pulse started it. And most people on Pulse think Cocoon started it. Fact remains that Cocoon was invaded by Pulse. I guess we'll never know, haha. It's very interesting for character development, because no one knows anything for sure. Pulse won but was almost whiped out. The war was actually just stopped after Ragnarok, when the godess stopped them and turned them into crystal.
