"What about human nature?"
If everyone is naturally bad, how does it help anything to put them into power, and give them control of nukes and stealth bombers? We've seen what happens when you do that, and it's not pretty. Although, I disagree that humans are as inherently bad as the guys in congress and the White House. I think most people are decent human beings, and I think people would be even better if they were given not only given the chance to be better, but if they were put in a position where being a decent human being was essential to day-to-day activities.
"How would such a society defend itself?"
In general, such a society won't need to. It's much harder to claim you're liberating a country when the country is already as liberated as it can get. If it really came down to it, the US army is currently the most powerful in the world, and it can barely handle a population of 26 million people. How would a less powerful army handle an even larger country?
