First of all, Hamas has reached up to Jerusalem with its' rockets, that's more than half of the country under Rocket threat.
Secondly, many of them do fall, especially during barrages.
And thirdly, the mere notion that you are waiving away the fact that the population has to live under constant rocket fire shows your total bias on this. If you would've had to send your kids to a school under constant rocket fire, stop your life every day running for the closest shelter or live in a place under constant threat of terrorists invasion by hundreds of underground tunnels, you'd be singing a different tune.
It's all well and nice, from the safety of your ivory tower.
