To pull a stunt like annexing the West Bank and all the rest of it , would see Israel face the biggest onslaught of public backlash globally. People from all around the World would automatically stand shoulder to shoulder with Palestinians. Israel would ,by taking such actions, seal its demise. The World has had and heard enough from Israel...withdraw from the West Bank. You are no more able to defend Israel with it than you are without it. Missiles do the trick today. Doesn't matter how big your buffer zones are. When will Israel think in modern terms instead of thinking instead of 2000 yrs ago. No-one uses javelins and slingshots anymore. Fact is you are worse off in the West Bank...takes less time for missiles to reach the West Bank than to reach Tel Aviv. Your thinking is illogical.
