Calling AEW vs WWE a war is like calling AWA vs WWF a war in 1984. One side has more money, a much younger owner, and more importantly an owner not stuck in the past.
Vince is obsessed with bringing back the glory days of the mid 80's when it was his idea of wrestling, but King Kong Bundy failed in 1995, and the Dungeon of Doom failed at the same time, people didnt want 80's wrestling in 1995 let alone wanting to watch 80's wrestling in 2020. The Ultimate Warrior flopped in both WWE and WCW because people wanted to see better workers. Sure people make fun of Lex Luger and Hulk Hogan's wrestling ability, but they could work a 15-20 match and have it be pretty good, while the Ultimate Warrior could only squash people.
You cant sell people on a big muscle man fighting a broken down giant with a bad back like you could in 1987.
The Adam Cole thing is just completely damning, where Vince wanted to take NXT's biggest star and make him a manager because his completely obsessed with height despite the ratings proving that most people dont care.
