You cannot do a query using the title of the related post. This information is not stored, only the post ID is. It is possible if you copy the title of the related post and store it with the posts you want to search. Something like

add_filter('acf/save_post', 'copy_country_title', 20);
function copy_country_title($post_id) {
  // get the value of the country field
  $country_id = get_field('intervention_country', $post_id);
  $country_title = get_the_title($country_id);
  // now store this value in a new meta field
  update_post_meta($post_id, 'intervention_country_title', $country_title);
}

then you can use the new field intervention_country_title for your query
