Translate the following English sentence to French:
"I think, however, that instability is merely a symptom and that we should be looking at the underlying causes. I think that it is preferable to fight the causes rather than attempt to tackle the symptoms when this is probably not possible and when, as already stated, the measure concerned is pretty certainly at odds with the Treaty of Rome."
Mais il me semble qu'il s'agit d'un symptôme dont nous devons chercher les causes, qu' il est préférable de combattre les causes plutôt que d' essayer de s' attaquer aux symptômes, ce qui est sans doute impossible et, comme je l' ai dit précédemment, ce qui est certainement contraire au traité de Rome.
