Give them something to live for. Fat, happy people don't become terrorists. Israel has made settlement after settlement, displacing families and communities for decades. It's taken water and deprived people of free movement. What do you expect the Palestinians to do? Sit down cross-legged as Israel squeezes them dry, praising their existence? When a country does something demonstrably bad to some people, and doesn't listen to the grievances of those people, eventually the only course of action left is violence. This has been demonstrated time and time again. Hamas doesn't have the capability to send warnings, and if you look at the density of Gaza you'd see there isn't much space away from anything Hamas-related, meaning Israel has carte blanche to shoot wherever it wants and claim it was targetting Hamas. You usually make a lot of sense, but it seems you have been perverted by the usual media nonsense so common over where you are. Both sides suck, but only one side is actually fighting for survival, even if both claim so. Think.
