If Arafat accepted Clinton's Parameters a lot of lives would have been saved. He couldn't change. He couldn't make the transition from being a terrorits to becoming a statesman.
From Clinton's book on Arafat and the peace process at the end of Dec 2000:
"Right before I left office, Arafat, in one of our last conversations, thanked me for all my efforts and told me what a great man I was. “Mr. Chairman,” I replied, “I am not a great man. I am a failure, and you have made me one.” I warned Arafat that he was single-handedly electing Sharon and that he would reap the whirlwind.
In February 2001, Ariel Sharon would be elected prime minister in a landslide. The Israelis had decided that if Arafat wouldn’t take my offer he wouldn’t take anything, and that if they had no partner for peace, it was better to be led by the most aggressive, intransigent leader available. Sharon would take a hard line toward Arafat and would be supported in doing so by Ehud Barak and the United States.
Nearly a year after I left office, Arafat said he was ready to negotiate on the basis of the parameters I had presented. Apparently, Arafat had thought the time to decide, five minutes to midnight, had finally come. His watch had been broken a long time.
Arafat’s rejection of my proposal after Barak accepted it was an error of historic proportions.
