Do we have what it takes?

In reading all the coverage about Neil Armstrong and his life I am reminded of how incredible the Apollo program was.  The Apollo 11 computer was less powerful than a typical smart phone.  That was hi tech then but now we look back at it with amazement.  The astronauts, NASA, and the country had a confidence in their ability to come out on top, to achieve.  To do whatever it took to reach their goal.  Do we still have that?  Or do we hide? Are we timid? Now we say, its impossible because of this or that but going to the moon was impossible when JFK challenged us to do it anyway.  They had the heart and strength to make it happen.  Does America still have that same kind of heart and strength to overcome the challenges we face today?
