French on Algeria's Football team?

In the world cup; game last year, one of the announcers stated that most of the players on Algeria's team are from France, but either one or both of their parents were Algerian and elected to represent Algeria. He even said most previously played for the French U20 and U17 squads. How should Algerians feel about this? Now if all the players hold residences in Algeria then that's another thing. But if they are born in France live in France? Now I don't know if that is a case. Maybe all hold residences in Algeria, maybe none. As an American I understand this a little. Jermaine Jones was born in Germany to a German mother and a American father (African American). At first he played for Germany, but had problems with the coaching staff so he switched to USA. I really don't know how I feel about it. I guess I just kind of look the other way. But maybe this is a problem in world soccer. What do you think?
