Most of these are historical events or something totally out of your control. (You want to take down Mossad single handedly?) One thing that is well within your control is not genitally mutilating your sons (or circumcision, as they call it) and informing others not to genitally mutilate their kids. Start with what's within your control, then move on from there. You can't change the world overnight, but you can change it little by little.
