There is far more open land than inhabited land.
Hamas' missiles are indiscriminate and illegal.

They are aimed at towns in the hope of murdering ordinary folk and their children.
And, when they use precision weapons, suicide bombs, they explode them on buses crowded with ordinary folk and their children.
