Is Hamas even a target anymore? In 4 days Operation Protective Edge took the life of 114 people, 88 of which were non combatant civilians [1]. They even managed to destroy a centre for disabled people. [2] That's a quite a big margin of error for one of the most advanced armies on the planet.
What people never mention is that they only target the sites that rockets get launched from. It's a cheap propaganda win for Hamas to launch rockets from football stadiums and hospitals.
There is an issue of impartiality on your sources (at least the Guardian), it's one of the better newspapers but is still pretty biased towards Palestinians.
Hamas weapons are and have always been the target.
They store these weapons in houses, in mosques, in hospitals in the hopes that civilians die and then useful people like you come and post these comments.
