Is Undersecretary of State Nicholas Burns Holding President Bush Responsible for Abu Ghraib?

His logic with respect to the alleged Iranian government culpability for Iranian munitions is noted here:

I’ll resist the temptation to draw an organizational chart, for obvious reasons. They’re part of the Iranian defense and intelligence establishment. They’re a major part of the Iranian government. Therefore, the actions of that force are the responsibility of that government. If that force is supplying technology for Shiite militants, that government is responsible.

The military police and the CIA officers at the Abu Ghraib prison were part of the American defense and intelligence establishment. Do we need to draw an organizational chart for the Undersecretary? Just how desperate is President Bush to launch us into another war that will make us less safe?
