why do Palestinians want another state?

every single attack that has been conducted on israels since 1948 by hamas or palestine supporting terrorist groups for eg

  • Munich Olympic Massacre (1972) killed 11 athletes by fatah
  • Coastal Road Massacre (1978) killed 38 by fatah
  • Afula Bus Bombing (1994) killed 8 by hamas
  • Dizengoff Center Bombing (1996) killed 13 by hamas
  • Sbarro Restaurant Bombing (2001) killed 15 by hamas and islamic jihad
  • Park Hotel Bombing (2002) killed 30 by hamas
  • Pat Junction Bus Bombing (2002) killed 19 by hamas

these are few famous bombings and massacres that were conducted against israel and they still want a different/separate state ? what basis do they have when all they have done is create violence and terror , not to mention the war against israel just after the independence in 1948.
