The player in Paradox games still have to play on "operational" level when his armies arrive to the front his country has with the enemy. From there it's all operational. Every maneuver and every decision about engagements. It's shitty and not detailed at all, but still.
What makes the game strategic is that the player has to bother with production, groupings, troop distribution, etc. Just because the wars would allow better control on the events of the fronts it wouldn't make it an operational game overall.
