Autofill a Field Based on Another Choice Field

Hello, I have an entity called Prospect. In that entity, I have a field/column called Country (dropdown Choice field synced with Global Choice named 'Country'). Once the user selects the country from the list, there is another field called Affiliations which should show which countries are affiliated with that selected country.

I have the list of countries affiliated with each other based on The 27 Sub-Regions of the World - OBJECTIVE LISTS

For example, if I select United States in 'Country' field, 'Affiliations' field should show Canada, Australia, New Zealand, Great Britain, and Ireland.

1) Should 'Affiliations' field be synced with the same Global Choice 'Country'?

2) How can I accomplish this using JS? I know I can hard code it as below but it's obviously not optimal:

var countriesAssocitions = {
//Afghanistan
  4: [139, 198],
//Albania
  8:[158],
//Algeria
  12: [17],
//American Samoa
  16: [155, 47],
//Andorra
  20: [32],
//Angola
  24: [140],
//Antigua and Barbuda
  28: [47],

  31: [21]
 //etc
 }

where every value on the left represents the index of a country from the global choice 'Country' and the indices on the right are those of the affiliated countries. \

Is this the right way to go about it or is there a better way such as creating an array for every group of affiliated countries (there are 27 groups)?
