I assume you are attempting to translate from the French text into English: "Undoubtedly, understanding this country fully is a difficult proposition and, at best, all efforts to do so will only help us resolve some of the ambiguities." I have not translated the French text literally but have instead used different phrases in English which capture the sense of the French text better (in my opinion) than a literal translation would.

Connaître ce pays complèment est, sans aucun doute, une tâche très difficile. Même dans des conditions optimales, toutes tentatives ne pourront que nous aider à résoudre seulement une partie des ambiguïtés.
