Anyway, as far as I know, although my country has committed its share of horrible massacres around the world, none of it has happened in my lifetime... I just hope it'll last.

(not all are Iraq, but you get the picture)
The modern military recognizes the need for PR. Abu Ghraib was mostly still pictures because it was mostly leaks--press was allowed nowhere near the place. Contrast this with videos of Hussein's statue being pulled down or the "Mission Accomplished" press conference
If you cherry-pick specific instances, sure, there was negative coverage of the Iraq War, but the big picture of Iraq War coverage versus Viet Nam War coverage is very different.
