It doesn't. The whole point of self-amplification is that it's a gift that
keeps on giving. While -- currently -- prohibitively costly to develop the
deployment is trivially easy -- a few frequent-flying businesspersons
would do. A population of agents stochastically sampling behaviour space
will eventually find the big red button and push it.

Evolutionary we're programmed to hurt back when you're attacked. So it's 
even rational; from a tit for tat selfish gene strategy. Apoptosis is okay 
if you're an organism, it sure sucks if you're a cell.

I never claimed it's a military tactic. It's just about killing people.

I am a single individual, or a small group. I have no population.

The specific scenario I described is most assuredly not there. In fact
there might be a single potential pathogen combining the salient
characteristics of a common cold and HIV lurking in some biodiversity pool
just about to be drained, but I'm not holding my breath (cough, cough,

HIV was not adapted to people. You'd be most likely dead or dying right
now if it spread via aerosol infection as easily as common cold. It would 
cull 50-80% of the entire world population before it had a chance to

Yes, I explicitly mentioned a family of unrelated engineered pathogens
released synchronously. There was a reason for that. No one can win all
ten rounds of molecular diversity russian roulette, played simultaneously.  
The only way to win is not to play.

Four cheers about having been lucky, rather.

I doubt it. The models indicate modern urban societies would not be hit 
hard. It sure could be a scourge elsewhere.

Bush said that God is taking sides in a conflict on TV, with a gleaming
beady eye. Judging from his Science policy it seems that his mind is quite
fried on God.

Sure, he is rational.

What makes you think I was talking about any war? I was describing a 
specific kill mechanism. If you're feeling bored you can run a probability
