A good summation from the Times of Israel:
To put it succinctly, Hamas is doing its best to kill any and all of us in Israel, while cynically seeking to protect itself from attack by emplacing its offensive capacity among Gaza’s often unwitting civilians. And Israel is doing its best to prevent its citizens being killed, while trying to thwart the attacks without harming Gaza’s civilians. There’s the relevant asymmetry.
