here's my 2 cents worth: in an episode w/ Bill Maher at Real Time w/ Bill Maher, he said in TopGun Marvick, Tom Cruise refers to the enemy as "The Enemy" w/o mention whether they are Russian, Communist china etc. That's the culture today, that no actor will piss off any race, group, gender etc. So no 1 actor will step on the toes of any group, people, countries etc.
The original TopGun did that as well, it isn't a recent thing. Though you can guess who the enemy is based off specific details. The Markings are on the enemy aircraft in the first movie look Soviet and use Russian names, and the enemy in Maverick is probably an Iranian group because of the F-14s, they're the only country in the world other than the USA to operate that aircraft.
