>>My favorite JFK quotation, even ahead of "Ask not...." and "Ich bin ein Berliner" (I am a jelly donut) was in a little noted speech in October 1963. "We all share this small planet. We all breathe the same air. We all cherish our children's futures. And we are all mortal."

>Where are those kinds of speeches today?

Everywhere. Open any political speech (better from a your country politician) and read it (i mean literally read it). Number of words is limited in any language and all niceties are well known by speechwriters.
