Don't worry about this world; it is not broken. And don't worry about others. You worry more about them than they do. There are people waging war; there are people on the battlefield who are more alive than they've ever been before. Don't try to protect people from life; just let them have their experience while you focus upon your own experience.
I had a very strong feeling about the Vietnam War, and I had a strong feeling about participating in it. The military draft was in place, I was summoned for a physical exam, and I was either going to be classified as fit for military service or make my objection to it. So I made my objection to it.
Never, never, never believe any war will be smooth and easy, or that anyone who embarks on the strange voyage can measure the tides and hurricanes he will encounter. The statesman who yields to war fever must realize that once the signal is given, he is no longer the master of policy but the slave of unforeseeable and uncontrollable events.
There will one day spring from the brain of science a machine or force so fearful in its potentialities, so absolutely terrifying, that even man, the fighter, who will dare torture and death in order to inflict torture and death, will be appalled, and so abandon war forever.
