A lot of races in WoW are related to existing cultures : Tauren to Native Americans, Centaurs to Mongols, Dwarves to Celtic peoples (Irish, welsh, scots), etc. Could we consider the Goblins as the Americans of Warcraft ? Capitalism, the highway in Azshara and Kezan, the sprawling metropolis in Kezan, the mount Rushmore-type scuplture in Azshara, the casino and golf course, their taste for motors, explosives, and Vegas-style tackyness... Looks pretty much American to me.
