Algeria and Jews: Qu'est-ce qui se passe?

Clementine forwarded me another article about Algeria and Jews, this time only accessible to those who can read French. For those without that highly marketable skill, the gist of the article is not so different from the one in Haaretz, but the end adds a new twist. The problem for the Algerian minister is not just with Sarkozy and his slight Jewiness, but with another potential visitor, Algerian-Jewish singer Enrico Macias: "Enfin, il déclare que la «venue d’Enrico Macias est une provocation»," but why? Why would the visit of this singer cause such a fuss? Because it would pose problems. But why? Via Wikipedia, I found this link to an article explaining that the singer's pro-Israel views are the issue, along with some past actions of his brother-in law (?). Basically Enrico Macias, born in Algeria, now living in France, is considered a representative of Israel.

What's going on?
