Vertaling van "eyes everyone here is nothing but common sense—we could perhaps " (Engels → Frans) :

Had this simple principle been upheld—a principle that undoubtedly in the eyes of everyone here is nothing but common sense—we could perhaps have talked business, so to speak.
Si on avait respecté ce simple principe qui, sans aucun doute pour tout le monde ici, est le gros bon sens, on aurait pu peut-être parler business, si on me permet l'expression.
