Yoram, You need to review your history. The Israeli Iron Fist Policy was started in the 1970's under Begin. The point was to crush any semblence of Palestinian national aspirations. Checkpoints and Roadblocks have been a fact of life in the territories since the 1970's. When you steal land in the West Bank, build Jewish only settlements, kill on sight anyone who carries a Palestinian Flag (this was policy before Oslo)...of course, you are going to have a security problem... It may be convenient for you to beleive Israeli policy is purely self defensive...but your belief is not based on reality. Let's start with one concrete policy statement from Israel: We will withdraw to the 1967 borders provided we get sufficient security arrangements... Do believe any Israeli leader can say this honestly? I haven't heard them...
