The building is important architecturally, historically and symbolically... If it saves even one jewish child from being nailbombed... I say raze it to the ground.
Do nothing that gives the terrorists any hope of rescue, or retrieval... wipe them out. We know they are in there. Tear Gas them, and then end it. Cut off the power and use night vision to infiltrate the compound. Do whatever it takes to arrest the nailbombers of little children.
There will be no peace or palestinian state till those who deny Israel's right to exist and live securely are gone. Sad to say, the musli think hiding in a Church will save their murdering hydes... if it does, they will do it again and expand on the concept even more the next time.
Take away all chits from their collection of terrorist tricks. End the siege, storm the building. It will be over tomorrow. I am guessing.
