Bush's famous explanation for 9/11 was a new low in American politics. It was a lie, obviously, but it wasn't even a good lie. We were watching, live, the last stage of a fifty-year decline in the performance standards of the White House's propaganda professionals. Once upon a time, in the days of FDR and Truman and Ike, the president was like a cross between Superman and God, the descendant of George Washington, who could not lie. Then Kennedy was shot and the Warren Commission came along (bringing with it a whole cottage industry of Kennedy mudslinging) and we learned that if the president was not a liar exactly, he was sure getting a lot of pussy that he never told us about. Then came Nixon and Watergate, and by the mid-seventies American had learned to check its silverware case every time the president finished giving a televised speech. Nixon's fall coincided with the CIA hearings and the awful revelations of all manner of crazed government behavior --exploding cigars for Castro, foot powder planted by the CIA to make the dictator's beard fall out. Northwoods. Gulf of Tonkin. By the middle of the decade, America knew: not only was its president a crook, but its government was a criminal enterprise, a potential suspect in any heinous unsolved crime. Who killed JFK, MLK, Malcom X? Who conspired to assassinate Salvador Allende? You knew who the first suspect was.
