The only way to create peace and harmony in our world is to live it. You will never make a peaceful Shalom filled world through violence. For the proof of my beliefs I point you to history. Find me one time when violence begat peace. Certainly you will find many a time when violence produced a pause in the ongoing violence. But you will never find a lasting peace produced through violence. Look at the following numbers and tell me I am wrong. Most of these wars were fought to create peace. None of them did!
