Israel's Retaliation

The world is condemning Israel for their attack on Hamas and "demanding" an immediate withdrawal. Where were all these nations during the past years when Hamas was continually firing rockets into Israel? Did any one of them "demand" Hamas to stop the rockets? If someone kept hitting you over and over and you kept telling them to stop or you were going to retaliate, but they never stopped, who is to blame when you finally get enough and pull out your baseball bat to get them to stop. Hamas has said for 60 years they would never ever except Israel. They send children into Israel with bombs attached to them to kill Israeli citizens. Why haven't these nations stepped forward to stop this anti-Semitic hatred and murder?
