The US nuked Japan to stop WWII, because an invasion would have cost both contrys far more. And we are the world cops, because no one else wants the job, or has the capibilty of doing it.
Yes, we have enemies. That will never change, but we can take them out when we need. Or just want to.
And if comes down to being forced to resorting to genocide to stop terrorism, so be it. We have to look out for ourselves, no one else will. Shouldn't have to, all the muslims I know are peaceful people, and hardcore American citizens.
All this is just aspects of being on top of the world's food chain.
And to shut the rest of you up, we do have our faults, and make our mistakes, just like everyone else.
But, we have grown to the point where we would never sanction the death of 5000 civilians, and expect the world not to respond. What happened will not go unpunished, and we will nail Bin Laden and all his cronies. It is just a matter of time.
Everyone on earth has a new enemy: Terrorism.
We work together to stop it, of we all will lose. It is us or them, pick your side, for there will be no bystanders in this World War.
