Translate the following English sentence to French:
"To return to the subject of enlargement, the Commission has taken a firm position, which is audacious but also resolute and responsible, for the objections raised are of two kinds: on the one hand, there is the desire to bring about enlargement immediately, which is a desire we share, but, on the other, there is the urgent need to specify clearly the implications of enlargement and the means by which it is to be brought about."
Pour en revenir à l'élargissement, la position de la Commission est une position forte et courageuse, mais aussi sévère et sérieuse, parce que les objections sont de nature double. D'un côté, on souhaite que l'élargissement ait lieu tout de suite, ce qui est également notre désir, mais de l'autre, on demande d'éclaircir les conséquences de l'élargissement et les instruments qui le permettront.
