---I'm not sure I understand what he's saying: Is Bush decision to attack Iran related to the commet?---
The aliens are mad at Bush because he is going to smite the Iranians, so the aliens are going to destroy the earth with a comet, prepositioned in 1995. To warn us of this they have been destroying crops in a fanciful geometric manner. How this all will help the Iranians is open to question. And just how is the left going to impeach Bush?
"...a comet, prepositioned in 1995"
Can we use a really big gerund to deflect this?
