Why don't they understand that if this is Allah's war, he could wipe out all Jews from the face of the earth with one swipe of his hand. He would not need mere humans to do his work for him. They should realise that the reason that the Israelis keep winning is because that is Allah's will, that is the only thing that can make sense.
Please note that I, personally, do not believe in the existence of any god. I am just trying to look at it from the perspective of those who believe in Allah.
