Firing those Rockets is useless and a hopeless acts ... May I ask why is Israeli is commit that massacre in Gaza if so? If they fired them with those harmless useless rockets, what more can happen if they had air-forces to bring down the buildings beyond 1967?

Just following the logic and here and asking...

Do not dwell in the past, do not dream of the future, concentrate the mind on the present moment. (Gautama Buddha)
