Subterfuge and dissembling are good in wartime. Only an inept commander wouldn't use both. If you look at the context, I was talking about how the concept of suicide bombers didn't exist. It is a recent fabrication.
Lastly, Islam is a highly decentralized cult, there is no clear authority or titular leader of any sort.
Not anymore. Decentralization does cause problems with religions. Christianity has the same problem, from churches that support homosexuals to "God Hates Fags," from peaceful groups to ones that advocate the murder of doctors, and long ago the same inter-sect warfare that you see in Islam today.
We have the basic problem that weak people will get drawn to the fanatical demagogues of any religion. There are a lot of weak people in the world, and they will do the leader's bidding.
