I think this was Bush 41's way of expressing extreme displeasure at the course that his son has charted. Remember also that two of Bush 41's top advisors wrote an Op-Ed piece against the second Iraq war, and that on Thanksgiving President Bush invited his father to the ranch for the holiday and then, without even telling him (can't the ex-head of the CIA and former President keep a secret?) he flew off to Iraq (the war his father seemingly opposed) to eat with the troops.
What?!
Back to the drawing board. Your analysis is way off the mark.
