Without giving away the plot, let's just say that he isn't convinced Bhutto will do a better job than Musharraf. Here is his clever segue:
Gen. Musharraf is – as George S. Kaufman remarked when the Germans invaded Russia – shooting without a script. But that's because he presides over a country that defies the neatness of scripted narratives. In the days after 9/11, George W. Bush told the world that you're either with us or against us. Musharraf said he was with us, which was jolly decent of him considering that 99.9999 percent of his people are against us.
That is the sort of decision elected leaders cannot make and hope to get reelected. Remembering that Pakistan has nuclear weapons, how would we feel about the mad mullahs taking over the country?
