It's not so much that this a great speech. (it is)
It's no so much that he was a great speaker. (he was)
It's that you can tell he meant what he said and cared deeply about his country and his countrymen and wasn't just telling us what government was going to do, but more so, inform the people on what the government isn't there to do. This speech carried so much more passion and depth than Kennedy's "Ask not what your country can do for you, but what can you do for your country". Reagan's inauguration speech was a well thought out plan with all scenarios taken into account. Have we had such a clear vision since?
