Proportionate response

According to http://en.wikipedia.org/wiki/V-2_rocket fewer than 1500 missiles were fired at London from about August 1944 until the last V2 was fired on 27 March 1945. All told fewer than 4000 V2s were launched......

According to http://en.wikipedia.org/wiki/Bombing_of_Dresden_in_World_War_II the British and US air forces bombed Dresden, Germany over a period of 2 days (13-15 February 1945) killing between 25,000 and 250,000 civilians.

So for 4000 rockets you are apparently supposed to kill between 25,000 and 250,000 civilians. I assume this means that for the more than 10,000 Kassam rockets launched from Gaza, Israel should kill between 62,500 and 625,000 civilians?
