From Kuhner's April 16 Washington Times column:

President Obama has disgraced the United States - again. During this week's nuclear summit in Washington, he bowed when greeting Chinese President Hu Jintao.

The act was not only shocking but revealing. Mr. Obama has come under intense criticism for bowing to leaders in the past - the king of Saudi Arabia, the emperor of Japan. But never before has America's commander in chief prostrated himself to a foreign tyrant on U.S. soil.

By bowing, Mr. Obama degraded and cheapened the office of the presidency; as commander in chief, he represents every American when meeting with other heads of state. He is supposed to embody the dignity of the Oval Office, reflecting our collective heritage as a self-governing, constitutional republic.

[...]

His actions reflect a fundamental, reflexive anti-Americanism - a profound contempt and hatred for his own country. Mr. Obama bows because it symbolizes America's need to “humble” itself on the world stage.

[....]

In short, Mr. Obama is bowing to the world. He seeks to establish a post-American multipolar order in which Washington is only one power among equals. He is a radical leftist, who welcomes the end of the United States as the world's last superpower. The very notion of “American exceptionalism” is repugnant to him - as it is to most multicultural progressives.

Mr. Obama's presidency can be distilled to one fundamental reality: He is presiding over America's decline, the slow but relentless erosion in its once-dominant economic, military and cultural position.
