http://www.commondreams.org/views03/0910-15.htm Consider what would happen if there was a virus or bacteria that only infected a particular type of person, killing, disabling, or sterilizing only those of a particular genetic profile. Consider the political leverage a nation would have if they could credibly threaten the extinction of all people worldwide with almond-shaped eyes, or the sterilization of everybody with a gene that tracks them back to a common ancestor or region.
Three years ago, Wolfowitz, Kristol, and their colleagues suggested this is something the Pentagon should be thinking about. Not just germ warfare, but gene warfare.
And it's not limited just to warfare: Imagine how genetic terraforming could replace diplomacy, could even render the United Nations irrelevant if entire ethnic groups were wiped out or could be controlled by the threat of extinction. Or how it could change the face of politics if an organism got loose that killed off all the people of a particular minority who tend to vote for a particular political party.
Genetically targeted weapons could change world politics forever, according to PNAC.
"And," their report notes, "advanced forms of biological warfare that can 'target' specific genotypes may transform biological warfare from the realm of terror to a politically useful tool."
