I learned last night from the Daily Show that the NY Philharmonic just played in North Korea. His guest, Madeline "Super-delegate" Albright called it a mission of "cultural diplomacy". This term was new to be, but low and behold, a quick internet search leads me to learn that it is a long standing tactic of international diplomacy. There are websites dedicated to it, including one that defined it this way:

Cultural diplomacy is a domain of diplomacy concerned with establishing, developing and sustaining relations with foreign states by way of culture, art and education...

Its interesting how powerful corporations and governments view culture. More proof that the NGO/nonprofit world should too. I'd still like to find some way to measure the power (some cultural diplomacy references described it as a soft power), and learn better how to harness it.
