corrections.
if they only reported what the govt told them, there would be no media source bashing the govt over anything.
also it was only the US media which was reporting that the US govt was "claiming to oust saddam because he had WMDs"
they never said there were WMDs. reporting what the govt says is different from saying it themselves.
also the rest of the world media stayed away from the propaganda war too.
What you're saying is opinion reporting, i.e. bashing is opinion. The facts and information reported is given to them by their governments.
Most of US seemed to be sure that Iraq had WMD. No "conspiracy theory" that?
