This comment below, from the piece, encapsulates the Giuliani bullshit machine for what it is:
"The Creator was GW Bush the timing of a withdrawal is irrelevant if the invasion never took place, as for doing the honorable thing did Colin Powel behave honorably before the UN? He is the one whose resignation could have stopped it all in its tracks"
End of story.
One good thing you can see from the comments is that many remember the sequence of tragic mistakes Bush and his cronies made, even after invading Iraq, which led to the creation of ISIS.
