The way I see it, we are compelled to deal with Islamic terrorism. We can't get around it, or ignore it. If we ignore it, it will grow to the point that it takes us over. The only way to deal with it is to deal with it!
There are two ways for us to be free of the threat of Islamic terrorism.
One way is simply to kill 'em all. Kill every last Muslim in the entire world. I don't think it would be possible for us to do that, there are 1.3 billion of them all over the Earth, but if we did, I don't think we would last a whole lot longer after that. Because we would know that we had killed all those people to get rid of, at most, a hundred thousand bad guys.
Then we would think of ourselves, rightly, as the kind of country that the Michael Moore's of the world say we are: a bad, bad country not deserving of existence. We would commit national suicide. I don't mean that every individual would kill him, or herself. Just that this thing we call the USA would cease to exist.
The other way is to get rid of the terrorists. Either by locking them up, or killing them, then change the conditions that breed them. The conditions that breed terrorists are despotic governments coupled with violent religious sects. I believe if we bring freedom and secular democracy to Muslim countries the religious fanatics will fade away.
It will be very hard, and it will be very messy, and it will take a long time. But relative to option one, it will be a walk in the park. At the end of that road, we will be secure and, as a side benefit, we will have the satisfaction of having freed millions of people from a Tenth Century existence.
