You need to iterate through the address_component array to find the entry with a type of "country". So something like:

// this is just looking at the first result - > results[0]
for (var i = 0; i < results[0].address_components.length; i++)
{
    var addr = results[0].address_components[i];
    // check if this entry in address_components has a type of country
    if (addr.types[0] == "country") 
        alert (addr.long_name);
}
