Return data from getJSON request and for loop to use in another function

I am having trouble with a seemingly simple problem. I am pulling data from an external JSON file and need to loop through all the objects and return their values to use in another function. Here is what I have so far...

var geo;

function getCountry(){

  $.getJSON('country.json', function(res) {
      return $.each(res, function(key, val) {
          for(var i = 0; i < val.length; i++) {
              geo = val[i].geometry.coordinates;
              return geo;
          }
      })    
  });
}

function mapIt() {

    getCountry();

    $(".container").mapael({
        map : {
            name : "world_countries", // name of JS file
        },
        plots: {
        'Random': {
            latitude: geo[0],
            longitude: geo[1]
        }               
    }
    });
}

mapIt();

Essentially, I am getting the latitude and longitude of a specific country with the first function and am trying to return the value (geo, which is an array containing the lat/long) and use it in the second function. I thought that I could maybe call the getCountry function within the mapIt function and it would store the variable.

Any suggestions/help would be greatly appreciated thank you so much!
