The national security musical chairs was made official today by President Barack Obama.

On stage was a daisy-chain of Washington insiders who have worn many hats over the years and criss-crossed different administrations. They all report to Commander-in-Chief Obama, who by comparison appeared a relative newcomer.

Secretary of State Hillary Clinton, a former senator and first lady, was there to welcome back into the fold Ryan Crocker, who was chosen to be ambassador to Afghanistan.

Crocker, a former ambassador to Iraq, had worked closely with General David Petraeus, who was nominated to be CIA director to replace Leon Panetta.

Panetta — a former congressman, White House chief of staff, and director of the Office of Management and Budget — was chosen for Secretary of Defense to replace Robert Gates, a former CIA director.
