We're all somewhat familiar with the body language dogs display when they greet each other. The dominant alpha male approaches directly, asserting his authority, while the beta male genuflects, crouches, tucks his tail, and may even end up on his back, exposing his neck in acquiescence, making sure the alpha male knows he has no intention of challenging him. With his "we will extend a hand if you are willing to unclench your fist" opening to the world's dictators, the President is exhibiting classic beta male behavior, in essence rolling over on his back and exposing his throat to them to make sure they know he has no intention of challenging their authority.

Joe Biden is a puppy. Barack Obama is a president.
