Does anyone actually believe a two state solution is possible in Israel-Palestine?

No. The idiot who decided to take away land in the possession of the Palestinians and give it to holocaust victims and Jewish refugees created a problem similar to that of the Native Americans and their European conquerors. Conquerors typically cannot be removed, and if their victims are allowed to remain anywhere nearby, they will be eternally angry. This will never really be resolved. The Palestinians are now being victimized by Hamas and their puppetmasters in Iran. You can create a Palestinian state, but you may as well call it Little Iran.
