Perhaps you need to watch some of Saddam's speeches, for he very much considered himself to be the leader of the faith as well. Iraq was secular only in as far as whoever ruled it made damned sure no cleric could attain enough power to be a threat to himself.
I've also watched the speeches of his theocratic counterparts, which I would suggest for a comparison of Baathist vs. just about everything else in the region.
An awful lot of Baathists ended up with Daesh after the US did it's de-Baathification of Iraq. So, in a way, his statement is probably correct as at least some of Saddam's old ruling gang are now doing the same duties as part of Daesh.

That's incidental to what he replied to: "Lol. Where was ISIS when Saddam was in charge?" Ie. ISIS the org.
There was no crazy theocracy when Saddam was in charge. It just so happened that IS came along paying for military experience and former army guys signed up.
