To most it is self-evident. It is the basis for the founding of this country. If you need an explanation or if you need convincing then you missed it.
To expect a country that has been brutally suppressed for 30 years and is presently under covert attack by the oppressors to suddenly turn into that Shining City on a Hill is either naive or dishonest.
But sir, you wrong me.
I don't expect any such thing.
In fact, if we wait 8000 years for it to happen, I don't expect it to happen.
Who are these "oppressors" of whom you speak? Are they, or their behavior, any different from the long and unhappy history of that barbarous region?
I think it's been more than 30 years. This is Babylon. This region is basically like it has been for 3000 years. I think it may be naive to think that it will EVER turn into a shining city on a hill.
