Bush's letter is worthless. The palestinians do not agree. You don't want unilateral actions right ? Ariel is right ibn the middle of palestinian populations ? why would Israel do that appart from creating another conflict with the palestinians ? why ? this is not 'natural growth', this is called 'occupation'. Israel uses and abuses military force perfectly knowing the palestinians cannot defend themselves. And when they do, Israel kills them.
