From Citizen Smash:
...President George W. Bush announced the unilateral operation to “liberate” the Red Planet earlier this month, declaring that Martian leader Marvin was secretly developing an Illudium Q36 Explosive Space Modulator in defiance of the United Nations Security Council Resolution 1541. Secretary of State Colin Powell, in a speech before the UN General Assembly last December, asserted that Marvin intended to use the weapon to destroy Earth because it was “blocking his view of Venus.” To date, no banned weapons have been found on Mars.
I'm with Krugman: can we just skip to the scene where President Bush dresses up as an astronaut and declares "Mission Accomplished"?
