Found this quote online while writing the Huntington story below:
"I couldn't help but say to [Mr. Gorbachev], just think how easy his task and mine might be in these meetings that we held if suddenly there was a threat to this world from another planet. [We'd] find out once and for all that we really are all human beings here on this earth together."
~Ronald Reagan, 1985
It seems to me that Reagan's understanding of both nationalist and universalist perspectives helped make him an effective, popular, and successful American President.
