US forces in the Persian Gulf were put on high alert for possible military action, after vice president Dick Cheney's office claimed that Iran was encroaching on his side of the car. "Iran continues to flout international norms by refusing to stay on its side of the back seat," said Cheney spokesperson Lea Anne McBride. "The division is clearly marked by the armrest down the middle." Critics say the announcement is an attempt to draw attention away from impeachment proceedings against the vice president by providing a casus belli for an invasion of Iran, although Cheney's office denies that the comments are provocative. It is the second time this year that Cheney has spoken out publicly against the Teheran regime, after accusing Iranian president Mahmoud Ahmadinejad in August of touching his stuff.
