Everyone on this thread is fully aware that both Nixon and Obama bowed to the Emperor of Japan.
Everyone on this thread has also elucidated you as to the many differences between the two; Nixon and the Emperor treated each other as equals. Obama acted subservient to the Emperor. Everyone has been clear on this.
So why the yawning? What else needs to be explained about the differences between the two scenarios? Enlighten us.
Yawn. Truly a boring issue. No traction, no meaning just boring.
