In the midst of being "lectured to" by Vladmir Putin at the G20 Summit, Obama felt his crusade to humiliate his country and show off his amateurism wasn't quite enough. So he made sure to add to his Bowing To Foreign Leaders Hits by doing so to Mexican President President Felipe Calderon.
Having a President who does not believe in American exceptionalism and constantly proving it in front of the world is starting to get on my nerves. Respect for foreign leaders is one thing but bowing before anyone is as unAmerican as it gets. We fought a war to disassociate ourselves from the kind of government where one man is expected to bow to another. But Obama doesn't understand that because he doesn't understand America.
All he wants to do is "show us our place" on the world stage, which certainly hasn't done anything to boost his popularity overseas anymore than it has here in the U.S. of A.
