I think for something like this they could afford the bother to have someone sign the emails. World leaders make pronouncements all the time and there is no problem with provenance. Everyone knows the issues and existing proposals/demands. You only have to cover whatever has changed. >From Russia's point of view how you make sure email with insane demands is not leaked? Any insane demands will be leaked by the other party. Nations can't have secret discussions that mean anything.
