They rejected independence in favor of war. Then they rejected it again in favor of war. Most recently they rejected the best deal that they could ever hope for again in favor of war.
Obviously they don't want peace. They cannot govern themselves. They must be governed.
If they ever did suceed in killing the Jews and gaining Palisine they would imediately be subjegated by another Arab state. Probable Sysria but maybe the Sysians would share it with Iraq and/or Jordan and or Eqypt etc.
In any case , The Palestinians would be slaughtered until they stopped resisting. The Palestinians are infinitely better off under Isreali occutation. At least under Isreali occupation they somtimes have the semblence of civil rights in fact many Palestinians have Isreali citizenship. Under any other Arab state (including one of their own making ) they would be brutally repressed and have virtually no rights.
