And Hamas' 50 rockets last week were in response to what? In the past week Israel has been targetting only militants and rocket launching sites (which sadly are often civilian areas), striking terrorists who have or were about to fire rockets into Israel.
This morning, a Hamas rocket hit a family's home in Southern Israel. I'm still waiting for Hamas' explanation as to what made the family a legitimate target.
UPDATE: Sunday morning the IDF struck terrorists in Gaza who were about to fire more rockets, killing two.
