There is no winner in war because nothing is right or wrong. There may appear to be a winner because they'll look victorious, but in reality they have not won anything. All the lives and waste of time being takes is not worth it. Philosophically the war will never be over. I don't know if you asking how the dispute between Israel V.S Palestine got started, but if you are I can tell you there are arguing over the land. Who has the right to the land is the question being asked. But the trouble stared during Bible times between Arbaham's 2 sons. I won't lecture on cause again I'm not so clear on that specific question being asked.
