I don't believe they all want to kill us. Sorry. It may come down to what you want, but until then, I will hold out for a better way. We have already killed scores of them. It hasn't done much good. Looks like we're fixin' to kill scores more, and I doubt it will do much good in the long haul.
There are plenty of our own who would do the same thing if they could get away with it.
That's because in your American dreamland you have no idea of who you're dealing with, and you have not witnessed the depths of depravity that humans are capable of. You've read about such things but trust me sweetcheeks, once you've seen it first hand you'll learn how real it is.
Their dedication to their "cause" and their hatred of us is such that they will kill themselves in order to express it. They're not going to stop either, not now or 100 years from now, until they're forced to stop. Old-world tactical military victories are not going to stop them. There are several thousand children waiting to take the place of every Taliban desert goon we kill.
Their perverted worldview runs like blood through their society. It's taught in their schools and in their mosques where instead of learning history and arithmatic, they're taught how to beat their useless, unredeemable heads against the koran. It's taught by parents to their larvae and it's encouraged by their political leaders.
Go ahead and play nice with those who explicity swear to destroy you, your family and your way of life. I'll continue to remember a family friend who on 911 was turned into something that resembles what you scrape off the bottom of your barbecue grill.
I'm sure it's nice on your home planet. Here on Earth we tend to be somewhat more realistic, which you'll find out after you observe for a little longer. Stay tuned.
The good thing for us is that muslim extremists have given us their playbook. It's called the Koran. It reads like The Godfather, only somewhat more brutal, and The Godfather wasn't about world domination. Check it out sometime.
