IMO, they achieved their political goals in Libya (overthrowing Gaddafi, destroying Libya which further destabilized Africa by allowing ISIS a foothold into Africa) while Iraq is a very mixed bag. They overthrew Hussein, but now there's greater Iranian presence within Iraq. Hussein might have had designs against the petrodollar, but he was also a check against Iranian influence within the region. Post-Hussein, Iraqi militias were launching drones against the Zionist entity while shouting "Labbayk ya Hussain" before the so-called ceasefire in Gaza. This would never happen under Hussein. I'm not sure to what extent a Hussein-led Iraq would agree to be part of the Axis of Resistance since Iran is such a key player. Overall, I would say that Iran probably benefited most from Syria with Assad and Iraq without Hussein.
