These were armaments calculated to do the job--and then some!
When you think about it, there is actually no reason whatsoever at this point to believe that he is still alive. (The fact that Saddam is incommunicado is potentially significant in that very regard.) The Iraqi's "live broadcast" of Saddam speaking doesn't add up, and we shouldn't count it as having any significance whatsoever.
In fact, several things about the broadcast positively argue that he is probably dead. According to one report I heard on TV, the "live broadcast" shows technical signs of being a videotape. I think the speech was pre-recorded as a generic rant for just such an eventuality. (Come to think of it, this would explain his tone. He was speaking as an unconvincing dead man.)
