Is violence ever a bad sign in Iraq?

Via Kos:

A military spokesman addressed the deaths of 11 more U.S. soldiers with the following explanation of how it's actually a good sign:

A spokesman for the U.S. military said insurgents are becoming more desperate as a democratic process increasingly takes hold -- "and desperate people are dangerous people."

I have a question for the spokesman, for Scotty McC and for the Pentagon as a whole: how much violence would be a bad sign? If 100 soldiers died in one day, would that mean that the insurgency was catastrophically detonating in a massive, desperate supernova?
