A Palestinian State would just continue doing more of the same it has been doing since 1948, namely the Killing of innocent civilians in the name of its beliefs.
A Palestinian state would just increase the worldwide nation tally of an Autocratic regime where corruption and immorality reign supreme. Making the passing of just resolutions in the defunct U.N. even more difficult.
Finaly a Palestinian state would very likely couse a nuclear war by allowing Iran to the doorstep of Israel.
Humanity can not allow that to happen!
