The unreasonable people on either side are those who do not see that people on the other side have a right to exist in the Land of Israel/Palestine.
The unreasonable Israelis are the radical right religious settlers on the West Bank who believe that all of the geographic Land of Israel (Palestine) was promised to the Jewish people by God. Hamas and other radical Islamic groups believe God is on their side and therefore acts of terrorism against Jews are justified. There will be no peace until religion is no longer used as a justification for evil and selfishness.
