As for security, every state has the right to self-defense, and Israel must be able to defend itself -- by itself -- against any threat. Provisions must also be robust enough to prevent a resurgence of terrorism, to stop the infiltration of weapons, and to provide effective border security. The full and phased withdrawal of Israeli military forces should be coordinated with the assumption of Palestinian security responsibility in a sovereign, non-militarized state. And the duration of this transition period must be agreed, and the effectiveness of security arrangements must be demonstrated.
