What Hamas had done by constructing these tunnels was a work of art.  It is so ironical that on one hand this nation is condemning the existence and the nature of operation of Hammas (terrorist organization), and on the other hand providing American cement along with other materials and financial assistance to the Abbas government which has joined hands with the Hammas to run the Palestinian governmental operations.  What Israel has been doing and will be doing is right.  It is the job of the Israeli leaders to protect the lives of Israeli citizens.  However, I am little bit pessimistic about the future of Israelis in that part of the world - one due to the wavering and abysmal foreign policies of USA and secondly, due to the sheer # of Muslims and the flow of petro-dollars to equip Hammas soldiers. In my opinion, time there is in favor of Muslims.  If you notice, each child is being brain washed and the seeds of hatred and ill-will against Jews are being planted in their brain.  These children will be tomorrow's suicide bombers.  Secondly, Muslims can afford to sacrifice thousands and thousands of their fellow Muslims, but Israel cann't afford to lose that number of people every time they have to fight with the Muslims.  Lastly, majority of Muslims in that region are unemployed and are being fed with the help of petro or American tax payer dollars.  So, they have nothing to lose whereas Israeli economy is flourishing and they cann't afford any disruption in their economic boom.  However, a barbaric solution to this problem is the application of nuclear arsenal by the Israelis to make Gaza a parking lot.
