David Hunter Miller, The Geneva Protocol
“ It is true that in the resolutions about the economic weapon in the Assembly of 1921, it was recognized that from practical points of view the application of the economic pressure cannot be made equally by all countries. But undoubtedly, subject to the practical difficulties mentioned, a definite obligation exists in Article 16 of the Covenant to impose economic sanctions against the aggressor, and, as I said, in my judgment this obligation is not changed by the Protocol; but it can now become an operative obligation only if and when the Council says so. ”
