Actually, you don't get it, and probably are incapable of getting it. A better analogy is that of the bank security: they are in control of the money and will not need to use their weapons unless threatened. Saddam is in power; he is not the one seeking power, much as your bank robber is the one seeking the money.
Saddam (as evidenced by his multiple assaults on Iran, the Kurds and Shiites of his own country, his Kuwait invasion of 91 where he also threatened to invade Saudi Arabia had we not stopped him, and subsequent attacks on Israel) is definitely a power hungry pyschopath.
In fact he is worse than the bank robber analogy. A better analogy is to compare him to a pyschopathic serial murderer. It's absurd to think you can appease him by just leaving him alone, and hope he will calm down and be good. He wants us to give him more time. If he could he would nuke NYC.
