Are we the baddies?If he is including civilians then yes. Surface targets are easy and their civilians have done nothing to deserve this.
Otherwise their leadership have been begging for decades to be decimated. The leadership that the US put in place. It would be quite a feat. Much of their leadership are secured waiting us out in missile cities that are immune to bunker busters and nukes. It would take a massive and prolonged ground assault to clear all of them out. Most people on all sides do not want this to become yet another multi-decade multi-trillion dollar war.
I would expect most of the civilians to flee the country and I have no idea who could or would accommodate 90 million refugees.
