With all the US war rhetoric, should Iran use the Bush Doctrine of Preemptive Defense and attack first?

i'd like to see the entire middle east subjected to the "bush doctrine"...kill 'em all, let allah sort them out...the arab culture is, in my opinion, malignant like a cancer and humanity would be much better off without it. it serves no useful purpose and contributes nothing positive. and NO, i never served in the military...
