I think you also need to practice your English as I never named a country to be the second most important. I can’t fathom how both you and Longhitter came to that conclusion. "It is the spoken language of two of the most important countries of the world with one of them being the most important." that deciphered tells you that one country is the most important not that the other is the second most important. If I had said "It is the spoken language of the two most important countries of the world with one of them being the most important." then I could see your point but I did not say that and all it leads myself to believe is that your comprehension of the language is not complete.
As I said above I do have a second language although not fluent which is in part because I don’t get to use if often and really only if I travel to the country that speaks it and it is not of as much use to myself as a non-native having English. Also I don’t have the benefit of regularly being immersed to the language like many persons who have English as their second language as a lot of the popular TV shows, movies and songs on the radio being in English and this obviously helps most non-native speakers and gives them regular access to practice and listen to the language. How many German or Dutch TV shows, movies and songs do you think people in the UK are given regular access to? I can tell you the answer is very close to zero unless one buys a satellite or so forth.
