1) Agree to the Saudi Plan of returning Israel to the borders prior to the 1967 war
2) Create a Palestinian nation on the returned land
Now for the fun part. Have Sharon and the entire western world inform Arafat that upon agreement to the above terms that a single terrorist act upon Israel will void the deal and Sharon is authorized to unleash every ounce of military force at his disposal. That Sharon is authorized to use said force for the purpose of destroying Palastine and its citizens and wiping it off the face of the earth. Israel shall then have claim to the land and it will be theirs forever.
