Would you have liked more Israelis to be killed? I tire of the comparison between the number of deaths. Israel has installed alert systems and shelters to protect its civilian population. Why don't you ask Hamas to hide in their tunnels, or at least use them to smuggle more food and medical supplies rather than weapons?
While at it, where was everyone when it was Israelis killed in the dozens and hundreds by Hamas terrorists shooting and exploding in buses and restaurants and markets... The uproar only came when Israel struck back in operation "Defense Wall" and built an actual wall. And guess what, terror attacks from the West Bank have been drastically minimized since then... And I believe the situation for Palestinians in the West Bank is better as well, not being ruled by a fanatical organization dedicated to destroying Israel by terrorism.
I can only hope this ends soon...
