Killing of innocents on any side is an abomination.
Palestinians vis a vis Israelis----read the history books. What is Israel, what is Palestine, what happened in 1948, what country was Jerusalem the capitol of in ancient days, what does "purchase of land" mean, and a lot of other questions.
Read all that, come to an objective decision and then realize that time, as tides, change things. Then decide right and wrong. But==big but== killing innocents is against the beliefs of all religions. Too bad some people are doing this for alleged "religious" reasons.
