A property of an organism enters into its life (and survival) in many different ways, some more salient than others. But there is no simple notion of its being "for" some function.
Noam ChomskyNorth Korea and China have proposed what sounds like a pretty sensible option that North Korea should end its development of nuclear weapons, the US should stop carrying out hostile military maneuvers on the North Korean border. The US immediately rejected it. Modernization program is a very clear example of how security doesn't matter. There is no gain in security but massive overkill of the adversary's deterrent capacity. The only consequence of it is to elicit the likelihood of a preemptive attack. And a preemptive attack leads to a nuclear winter world.
Noam ChomskyThe Bush administration has created an unimaginable catastrophe in Iraq. This should've been one of the easiest military occupations in history and they succeeded in turning it into one of the worst military disasters in history. They can't control it and it's almost impossible for them to get out for reasons you can't discuss in the United States because to discuss the reasons why they can't get out would be to concede the reasons why they invaded.
Noam ChomskyHillary Clinton was the one pressing the hardest for bombing, and look at what happened. They not only destroyed the country, but Libya has become the center for jihad all over Africa and the Middle East. It's a total disaster in every respect, but it does not matter. Look at the so-called global war on terror.
