So thats why 2000 civilians dies? Please, listen to yourself for a minute. You expect palestinians to just lay down their arms when they have been invaded? I dont know what world you live in, but palestinians certainly dont suffer from Stockholm syndrome. Maybe you would obey your oppressor? And please stop using the lame argument "hamas is palestines enemy" when Israel have occupied and oppressed the Palestinians before the formation of hamas. So in that sense, you can thank israeli terrorism for creating hamas.
What objectives? If you mean killing as many civilians in a densed area then yea, they are achieving their goal
