The question then becomes which sense of the word was intended by the drafters of the conventions, sense #1 or sense #2? Evidently the court decided that it was sense #1.

Unless the drafters of the Convention defined what they meant by "international", trying to decipher their intent without evidence is not the proper way to interpret a legal document.
Both definitions can be read in pari materia as there is no conflict between the two. International meaning "transcending national boundaries" is a common legal definition of the word and is in international common usage.
