Supposing the US (with or without coalition) had decided to press on into Irag in 1991.
saddam's downfall would have been blink away.
14 of his 18 states were in rebellion in the wake of the kuwaiti retreat. not only were there thousands of deserters
but the assaults against the state were initiated - at least in the southern city of bsra - by a now legendary (name
unknown

) tank commander who turned his gun against a large public portrait of saddam and blasted away.
what receives so little public attention is how the u.s. gov't miserably failed to support the rebellion. beyond doling out cheap rhetoric and empty promises, they did literally nothing.
it didn't take long to realize their assumptions about a quick iraqi coup d'etat were grossly over-estimated that the
rebellions in the south and north were crushed by saddam's republican guards, who survived the kuwait mess, more or less, intact. if i recall correctly, all the republican guard divisions were at least at 80% strength following the retreat and
redeployment.
