... of a country is not the way.
If we really feel threatened, we need to go after only those responsible, and not civilians, or entire countries.
Sure, we can destroy Afghanistan, but we know the real problem there is Bin Laden himself, and the Taliban.
We have to strike a balance when it comes to protecting our interests, and the interests of others. Our interests can be viewed as morally superior to those of terrorists, but we should never view them as morally superior to the interests of people who are not terrorists, but might not be our best friends in the world.
"Might makes right" is not the type of philosophy a civilized nation needs to live by in order to protect its interests. We cannot, and should not expect the rest of the world to conform to us because we can beat them into submission.
We need to control people who are a danger to Earth's societies, but we have to be careful in order not to permanently disturb a group of people just because their way of life is different than ours.
Abusing people and trying to convert them to "our way" is not the right way of going about things. By doing that, we lose entire perspectives on the world and supplant them with our own.
Just because we're not going to get immediate repayment for our charitable efforts, doesn't mean the efforts are not worth it.
It's a matter of nationalism. Nationalism can be a terrible thing. We put barriers between ourselves simply because of our geographical origin.
Invincibility can be terror.
