Didn't you know that in Release 3 of the RWM2000(Rover Weather Machine)there is software that creates Radical Islamists?
I read somewhere (NY Times perhaps) that during the 80's in beta testing, Bin Laden was created. Reagan was looking to put the RWM1984 version on a star wars platform and control the weather from space. Things went a bit awry.
IIRC in Version 1 Release 1 Modification 3x85 the RWM1984 created AIDS and using it from space accidently hit a small african monkey farm in Kenya followed by subsequent strikes in San Francisco, Grenwich Village and Thailand.
HIV (Halliburton Invented Virus) as it came to be known in some Liberal circles actually infected the central nervous system, turning peace loving people into hateful radical killers with no common sense.
And that is how you got Al Zawahiri.
So that's why the libs oppose missle defense. Silly me I thought it was because they didn't think it would be fair for us to be able to repel a missle attack when our enemies couldn't.
