Like I said, you clearly prefer to bury your head in the sand.
The Israel Situation: Rocket Attacks Increased During Truce
If you believe that 2,900 rockets, fired into Israel, DURING THE TRUCE (it was a TRUCE, not a CEASEFIRE) did not result in any devastating maimings and wounded (which is the whole design goal of Kassam rockets), then you must be terribly naive.
Do proportionally more Palestinians get killed - seeing as how Hamas cowardly uses civilians as shield, it seems unavoidable -- but you have Hamas to blame for that, not Israel.
