Translate the following English sentence to French:
"I should simply like to make two additional comments: the first, which is directed at Mr Berthu, who, unfortunately, is no longer present, is that, when I was talking about the fantasy of zero immigration, I meant that sometimes, the argument of zero immigration is used as a rhetorical instrument. It is also interesting to note that some leaders who use the argument of zero immigration in this way are also those who are largely responsible for immigration policies that are lax in terms of integrating immigrants into the societies that receive them."
La première, à l'intention de M. Berthu, qui, malheureusement, n'est plus là, pour dire que, lorsque j'ai parlé du fantôme de l'immigration zéro, c'est parce que, parfois, l'argument de l'immigration zéro est utilisé comme un instrument rhétorique, et il serait, d'ailleurs, assez intéressant de constater que quelques-uns des responsables qui utilisent l'immigration zéro comme instrument rhétorique, sont les principaux responsables des politiques laxistes en matière d'immigration en ce qui concerne l'intégration des immigrants dans les sociétés d'accueil.
