President Reagan states, "It is time for us to realize that we are too great a nation to limit ourselves to small dreams." This could be seen as him saying, "We're better than we think and it's time we see that." He then goes on to say, "We are not, as some would have us believe, doomed to an inevitable decline." This could be interpreted as him saying that "people believe that because of our current economic standpoint, we are doomed to fail. But that's not true."
So, this overall statement seems to best fit the idea of Americans overcoming the obstacles ahead of them. Hope this helped!
