Yes, the way it should work is that there should be different "bars" for different difficulty levels. Then the kiddies can play on Easy and get to beat up armies smaller than them all the time. The mid-level players are attacked by armies with approximate parity, and on "Hard" the AI attacks only when it has a clear advantage.
