I'm afraid i would have to disagree. Look at many of the ancient empires. Sure, most of them eventually 'fell' (if you want to call it falling, which is again debatable) in the end, but so does everything else. For a slightly more recent example, look at germany. Sure they were eventually defeated, but only since most of the rest of the world combined forces against them. Your saying reminds me of that old saw "Violence never solves anything" which is blatantly untrue.
