Even if this isn't the place to discuss national politic, as I said it nothing is doing without the OK of the palace, especially what about royal family, that is the way things go where the power is absolute
In second, about caricature, you interpreted the cartoon in a way, personally I didn't see it at all like this, the gesture of MY Isamel is the gesture of most of bridegroom in morocco, the king did the same one at his wedding (see this photo), and to say that the star in morocco flag is Davide's flag it is far-fetched, for me this caricature is a pretext, do you know that one of the most famous journalist of morocco, M. Khalid Djemai did a paper in this newspaper who he was critic again M6, because he doesn't allow Moulay Hicham to take the photo with all the royal family, he said in the last of his editorial “L’inimitié peut être perpétuelle, mais l’éducation doit être éternelle".
Personally, I think that this entire story is because one of more respectable journalist took position in favor of moulay hicham against M6, and not because this poor caricature and the palace give the argument of anti-Semitism because they know that people are very sensitive about this question
