Bush is responsible for Abu Ghraib:
From Bush's speech
Some say Iran's leaders are not aware of what members of their own regime are doing. Others say Iran's leaders are actively seeking to provoke the West. Either way, they cannot escape responsibility for aiding attacks against coalition forces and the murder of innocent Iraqis.
Let's do some substitution:
Some say Bush was not aware of what the U.S. military was doing in Abu Ghraib. Others say Bush did know and sanctioned the abuses. Either way, Bush cannot escape responsibility for what happened there.
