It has long been Israeli policy to kill as many Palestinians as they could get away with. Israel just pushed a little too far in the Gaza op and must now readjust for future killing sprees. In the Gaza op alone, Israel killed more than 20 times the number of civilians as have been killed by Qassams over their entire existence. Killing civilians does not address the problem, is immoral, and plays into Hamas hands. Still, killing Palestinians is something that Israel cannot resist.
