My Two Cents Worth
It was an elegant bow and, I think, totally appropriate. A bow in Japan is like a handshake in the U.S. It is not a sign of subservience, but of respect. The way people greet each other differs from culture to culture.
I, for one, am happy to see a president who is so international and so global that he can greet others in their style, naturally and beautifully. I am sure it comes from having grown up in the Aloha State, as well as in cultures and countries beyond his own. One day, I hope the Japanese get a prime minister who can, say, kiss the cheek of the French prime minister. Or touch noses with Inuits... or Moaris.
Some claim Obama does not represent the American people. I guess these people don't think Graciousness or Tolerance or Understanding of Differences are representative American values. That's too bad.
Two cents ain't worth much these days, but there it was.
