This last attack on the WTC was hardly our first experience with terrorism on our own soil, or against our citizens or property on foriegn soil. Our response to these attacks in the past has not been to just wring our hands. Our response in the past has been to drop a few bombs on someone. And the result of these responses has not been an end to terrorism. It has been that the attacks have increased in severity.

And my answer to your last paragraph is not the US. My answer is that no nation can do such a thing alone. We can only do it with the help of most of the rest of the world. And they with us. What has changed hasn't been just the fact that the US was bombed. What has changed is that much of the rest of the world sees themselves in our tragedy, and they have the same desire to solve the problem as we do. They understand, as some of us in the US do, that we have to do this together if we want it to get done.
