Sting in 1990

If Sting doesn’t get hurt at Clash X, does he win the title from Flair at WrestleWar 90, or would they have done it at Capital Combat with Robocop?  Would the Black Scorpion angle have worked if they had put the Scorpion over at Starrcade and revealed it to
be Flair after he won the belt, like with Moolah as the Spider Lady?

Sting was absolutely winning the title at WrestleWar.  The Scorpion angle was already dead and buried six feet under by the time they got to Starrcade and there was no saving it.
