So, in "The Lion King", Scar schemes up a way to convertly kill Mufasa and pin the blame on Simba in order to claim the throne. However, I don't think this was necessary consider the army he had and since Scar is a pretty smart guy I was wondering this.
If you watch the part where Scar sings "be prepared", he has like a bajillion Hyenas under his command. There are like at most 20-25 lions guarding pride rock. Instead of going about sneakily trying to take over, why doesn't he declare war and lay siege to pride rock with his Hyena army?
