A really interesting question to explore would be: What is the Ring for America today? Pride in our military prowess? Our wealth? Our (supposed) cultural superiority?
I think those things may be why we are like Boromir, but those traits are only the symptoms that made Boromir susceptable to evil... they are not the ring itself. If the ring were here, would we recognize it?
Well, speaking for myself, I take pride in our individual liberty, which makes possible our greatness. I don't see that as parallel to the ring.
But do you think we are too proud? An awful lot of folks on the left would like to cut us down to size, I know.
Although now that I think your words through a little, I guess you mean that we are not remembering to be thankful enough to God for our wealth and our achievments.
I'm not too religious, but I think I go along with that too.
Certainly, I believe that the individual liberty that is the basis of our way of life here has been essential to our remarkable success. However, our founding fathers believed that such liberty was derived from God, or at least was a "natural" right, which is much the same thing.
