There is a point of view which says that from an evolutionary point of view, wars are necessary. They get us unstuck from local minima. The misery and loss of life (always OF OTHERS) is too little a price to pay:

Holly, I'd like to cut you in, old man. There's nobody left in Vienna I can really trust, and we've always done everything together. When you make up your mind, send me a message - I'll meet you any place, any time, and when we do meet old man, it's you I want to see, not the police. Remember that, won't ya? Don't be so gloomy.

After all it's not that awful. You know what the fellow said – in Italy, for thirty years under the Borgias, they had warfare, terror, murder and bloodshed, but they produced Michelangelo, Leonardo da Vinci and the Renaissance. In Switzerland, they had brotherly love, they had five hundred years of democracy and peace – and what did that produce? The cuckoo clock. So long Holly. (The third man, Orson Wells)

(my usual Marxist diatribe: ) From a Marxist point of view: Capitalism's constant accumulation of capital causes the diminishing of returns and profits. Simply said: at regular intervals (cycles) too much capital is accumulated and floating around waiting to be invested (because this is what Capitalism is all about: max profit for your investment, capital does not rest) but there are fewer opportunities to invest it and harvest the Profit. This is because of lack of resources (e.g. material) and - a very realistic - limited consumer capacity: there is so much salami one can eat ("use" would be the politically correct way to say this). The solution is Capital Destruction. Best achieved by wars.

There are no easy options with 7 billion people on earth. The sheer number amplifies the ignorance and greed of the few. We are way past any "regulation" measures (in economy, military, environment). But the worst inmo is that Ignorance takes new forms and spreads faster among the Educated.

The laws of Physics and Probability (gosh! which one is more lethal in this case?) limit or prohibit our escaping to the stars. Therefore, make love before the war would be Epicurus answer to world peace. And I will go with it if there is a free lunch thrown in (biodegradable prophylactics goes without saying).
