Many of these clues do not yield a single answer on their own. However, once we start getting a few answers, it becomes apparent that they are all part of the NATO phonetic alphabet. The references in the flavor text to “Europe and North America” and “Victor and Sierra”, as well as the initials of the title all can help with this realization. From here, it’s just a matter of identifying which of the letters can go with each clue.
Sport = GOLF
A Montague = ROMEO
Showbiz award = OSCAR
School _______ = UNIFORM
Character in Peanuts = CHARLIE (Brown)
The Marriott = HOTEL
Northerner = YANKEE
Previous Vice President = MIKE (Pence)
What a team might wear = UNIFORM
Spanish potato = PAPA
Parent = PAPA
You might hear it again = ECHO
Argentinian dance = TANGO
Reading out these as the letters they represent gives GROUCHY MUPPET, which is naturally OSCAR. Special shoutouts to a particular Oscar, who celebrated his birthday at the beginning of March, a few days before this puzzle released!
