We study history to learn from it. If we study history and decide to learn from the mistakes of the past we can make sure we don't make the same mistakes in the future. History has made almost every mistake possible and we have the choice to listen to it or not. If we listen to history and not twist the facts we are more likely to succeed in the future. We can see what went wrong and apply it to our lives. We make mistakes in our lives and we learn from them. We should do the same with history.
The conflict between Israel and Palestina began with the creation of the State of Israel in 1948 and the conflict can be traced back when the Arabs opposed to Jewish immigration to Palestine after the end of WWII, as well as sectarian conflict in Mandatory Palestine.
The conflict is basically for the land when United Nations recommended the partition of Palestine into two states one Jewish and one Arab. The Jewish accepted the UN resolution but not the Arabs.
True, the interfaith movement has grown by a lot.
